Answer:
$2.21
Step-by-step explanation:
You want to know the savings between using a $10 off coupon and taking a 15% discount, if the tax rate is 10.3%.
CouponThe price with the coupon is ...
$79.99 -10.00 = $69.99
When tax is added, the total becomes ...
$69.99 × 1.103 ≈ $77.20
DiscountThe price with the discount is ...
$79.99 × (1 -0.15) ≈ $67.99
When tax is added, the total becomes ...
$67.99 × 1.103 ≈ $74.99
SavingsThe savings by making use of the discount is ...
$77.20 -74.99 = $2.21
The total savings between the coupon and the discount is $2.21. That is, you save $2.21 more by using the discount instead of the coupon.
__
Additional comment
The question seems a bit ambiguous. The word "or" suggests you cannot use both discounts. If you do, the total amount saved will depend on the order in which they are applied.
You get the best result by taking the $10 off the sale price. Doing that gives you a total savings of about $24.27 off the normal price with tax.
what is a congruent triangles worksheet
A congruent triangles worksheet is a type of educational resource that provides practice problems and exercises for students to work on to help them understand and apply the concept of congruent triangles.
The worksheet typically includes a variety of problems, such as identifying pairs of congruent triangles, determining congruent sides and angles, and applying congruence postulates or theorems to solve problems. The problems may involve using the side-side-side (SSS), side-angle-side (SAS), angle-side-angle (ASA), or hypotenuse-leg (HL) congruence criteria.
Congruent triangles are triangles that have the same size and shape. In other words, they are identical in every way except for their position and orientation in space. Understanding congruent triangles is important in geometry, as it can help students to solve problems involving triangles, as well as more complex geometric figures.
Worksheets are a useful tool for students to practice and reinforce their understanding of congruent triangles, and can be used in the classroom or as homework assignments.

the product of 5/8 x 6/15
Answer: 1/4
Step-by-step explanation:
To find the product of two fractions, you simply multiply the numerators together and multiply the denominators together. That is:
(5/8) x (6/15) = (5 x 6) / (8 x 15)
Simplifying the numerator and denominator by dividing both by their greatest common factor, which is 2, we get:
(5 x 6) / (8 x 15) = 30 / 120
Further simplifying the fraction by dividing both the numerator and denominator by their greatest common factor, which is 30, we get:
30 / 120 = 1 / 4
Therefore, the product of 5/8 and 6/15 is 1/4.
Answer:
To multiply two fractions, you simply multiply their numerators (top numbers) and denominators (bottom numbers), respectively.
So, 5/8 x 6/15 = (5 x 6) / (8 x 15) = 30 / 120
To reduce this fraction to its simplest form, we can divide both the numerator and denominator by their greatest common factor, which is 30.
30 / 120 = (30 ÷ 30) / (120 ÷ 30) = 1/4
Therefore, the product of 5/8 x 6/15 is 1/4

Total Surplus The sum of consumer surplus and producer surplus is called the total surplus; it is one measure economists use as an indicator of the economic health of a society. Total surplus is maximized when the market for a good is in equilibrium. A camera company estimates that the demand function for its new digital camera is and the supply function is estimated to be here is measured in thousands. Compute the maximum total surplus.
The total surplus at the equilibrium point is: $200,000
This is the maximum total surplus that can be achieved in the market for the digital camera.
To compute the maximum total surplus, we need to find the equilibrium quantity and price in the market for the digital camera, and then calculate the consumer and producer surplus at that point.
First, we need to set the demand and supply functions equal to each other to find the equilibrium quantity:
50 - 2P = 2P - 10
4P = 60
P = 15
Substituting this equilibrium price into either the demand or supply function, we can find the equilibrium quantity:
Q = 50 - 2(15) = 20
So the equilibrium price is $15, and the equilibrium quantity is 20,000 digital cameras.
Next, we can calculate the consumer and producer surplus at the equilibrium point. Consumer surplus is the difference between the maximum price a consumer is willing to pay for a good and the market price, summed over all consumers in the market. Producer surplus is the difference between the market price and the minimum price a producer is willing to accept for a good, summed over all producers in the market.
The demand function gives us the maximum price consumers are willing to pay for each quantity of digital cameras:
P = 25 - 0.5Q
So at the equilibrium quantity of 20,000 digital cameras, the maximum price consumers are willing to pay is:
P = 25 - 0.5(20) = 15
This is exactly the same as the market price, so there is no consumer surplus at the equilibrium point.
The supply function gives us the minimum price producers are willing to accept for each quantity of digital cameras:
P = 0.5Q - 5
So at the equilibrium quantity of 20,000 digital cameras, the minimum price producers are willing to accept is:
P = 0.5(20) - 5 = 5
The market price is $15, so the producer surplus is:
(15 - 5) * 20 = $200,000
Therefore, the total surplus at the equilibrium point is:
$200,000
This is the maximum total surplus that can be achieved in the market for the digital camera.

how to read 2/10 net 30 ?
2/10 Net 30 represents credit given to the buyer for the sale of goods or services. 2/10 net 30 means that the customer gets a 2% discount if the outstanding balance is paid within 10 days. Otherwise, full payment is due within 30 days.
2/10 Net 30:
The terms and conditions of the transaction are set forth in the purchase order and the corresponding invoice. These terms include terms of credit between the seller (also known as the payee) and the buyer (also known as the payer). A typical net credit period of 30 means the balance must be paid within 30 days of the invoice date. 2/10 Net 30 (also known as 2 10 Net 30) means that if a buyer pays within the first 10 days, their balance will be reduced by 2%. So "2" is the discount amount (2%) and "10" is the due date (10 days).
For example, if your company purchased $500 worth of goods or services on June 1st, you have entered into a loan agreement with the seller. If your company pays the net amount between June 1st and June 10th, you get a 2% discount, bringing the total amount to $490.

a first time homebuyer is given the choice of two loans: loan a: 390,000, 15 year-fixed, 4 discount points, M=$3,509.71. loan b: 390,000, 15 year-fixed, 0 discount points, M=3,659.86. how much does the hole buyer save in total by choosing loan A? a) 27,027 b) 11,427 c) 26,351.02 d) 42,627.05
The amount the the home buyer saves in total by choosing Loan A is most closest to $11,427. The Option B is correct.
How much does the buyer save by choosing Loan A?In order to compare the total cost of each loan, we need to consider both the monthly payment and the discount points.
For Loan A, we have Loan amount: $390,000, Loan term: 15 years, Discount points: 4 and Monthly payment: $3,509.71. For Loan B, we have Loan amount: $390,000, Loan term: 15 years Discount points: 0 and Monthly payment: $3,659.86.
The total cost of Loan A is the sum of the discounted upfront cost (discount points) and the total of all monthly payments over the life of the loan:
= (4% of $390,000) + ($3,509.71 x 180)
= $15,600 + $631,948.80
= $647,548.80
The total cost of Loan B is the total of all monthly payments over the life of the loan:
= ($3,659.86 x 180)
= $658,574.80
Now, the amount saved by choosing Loan A over Loan B is the difference between their total costs which equals:
= Total cost of Loan B - Total cost of Loan A
= $658,574.80 - $647,548.80
= $11,026

The antiderivative of 1x (or simply x) is (1/2)x² + C, where C is the constant of integration. In other words, the antiderivative of x is the function whose derivative is equal to x.
This is a basic result in calculus, and it is derived using the power rule of integration. The antiderivative of 1x (or simply x) is the function whose derivative is equal to x. This function is (1/2)x² + C, where C is the constant of integration. To find the antiderivative, one can use the power rule of integration, which states that the antiderivative of xⁿ is (1/(n+1))x⁽ⁿ⁺¹⁾ + C. In the case of x, n is equal to 1, so the antiderivative is (1/2)x² + C. The constant of integration represents the family of functions that have the same derivative, so it is added to the antiderivative to reflect this.

What is the square root rule?
The square root function involves the square root symbol √ which is mostly read as "square root of", the rule says that the square root of a number 'x' is a number 'y' such that y² = x.
We know that the square root of a number can be either positive or negative, but while defining the square root function, we restrict its range to be the set of all positive real numbers and hence making all square roots possible to be positive.
If the range for the square root of a number is set to be positive as well as negative it wont be a function that is why there is a restriction to the range of this set allowing only positive real numbers.

Find the coordinates of the circumcenter of AABC with vertices A(9,-4), B(5,-2), and C(0, -1).
The coordinates of the circumcenter are
Coordinates of the circumcenter are (7.7, -6.6)
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
we first need to find the midpoint of each side, and then find the intersection of the perpendicular bisectors of each side.
Midpoint of AB is (7, -3)
Midpoint of BC is (2.5, -1.5)
Midpoint of AC is (4.5, -2.5)
The slope of the line passing through A and B is:
m= (-4 - (-2))/(9 - 5) = -1/2
the slope of the perpendicular bisector is 2
By point slope form
y - (-3) = 2(x - 7)
y = 2x - 17
And the equation of the perpendicular bisector of AC is:
y - (-2.5) = -1/2(x - 4.5)
y = -1/2x + 5
Now 2x - 17 = -1/2x + 2.25
2.5x = 19.25
x = 7.7
Substituting x = 7.7 into the equation for the perpendicular bisector of AB, we get:
y = 2(7.7) - 17
y = -6.6
Hence, coordinates of the circumcenter are (7.7, -6.6)

A rectangular aquarium 7 m long, 1 m wide, and 1 m deep is full of water. Find the work needed to pump the top half of the water out of the aquarium by raising it over the top of the aquarium. (Use the facts that the density of water is 1000 kg/m3 and g ≈ 9.8 m/s2.)
The work needed to pump the top half of the water out of the aquarium by raising it over the top of the aquarium is 34,300 J.
How to find the work needed to pump the top half of the water out of the aquarium?First we need to calculate the total amount of water that needs to be lifted and the height it needs to be lifted to.
The volume of water in the aquarium is given by:
V = 7 m * 1 m * 1 m = 7 m^3
Since we need to pump out the top half of the water, the volume of water that needs to be lifted is:
V = (1/2) * 7 m^3 = 3.5 m^3
The mass of the water can be calculated as:
m = V * density of water = 3.5 m^3 * 1000 kg/m^3 = 3500 kg
The height that the water needs to be lifted to is equal to the height of the aquarium, which is 1 m.
The work needed to lift the water can be calculated using the formula:
W = m * g * h
where
M is the mass of the water G is the acceleration due to gravity (9.8 m/s^2) H is the height the water needs to be lifted toSo, the work needed is:
W = 3500 kg * 9.8 m/s^2 * 1 m = 34,300 J (joules)
Therefore, the work needed to pump the top half of the water out of the aquarium by raising it over the top of the aquarium is 34,300 J.
