Find the simple interest for the following. Use ordinary time (360 days). Round to the nearest cent.
$34,000 at 7.5% for 100 days
When the principal is $ 34000, the rate is 7.5%, and the time period is 100 days, the simple interest is $ 698.63.
what is simple interest ?Increase the investment by the lending rates, the length of time, and other factors to arrive at simple interest. Simple return = money + interest + hours is the selling formula. This method makes it easiest to calculate interest. The most conventional technique to figure out interest is as a portion of the principal sum. He will indeed pay his share of the 100percent interest, for example, if he buys $100 from just a friend and offers to pay it back with 5% interest. $100 (0.05) = $5. When you borrow more money, you should pay interest, then when you give it out, you must charge interest. Interest is often determined as an extra component of the loan total. The interest on the loan is this percentage.
given
r = R/100 = 7.5%/100 = 0.075 per year,
putting time into years for simplicity,
100 days ÷ 365 days/year = 0.273973 years,
then, solving our equation
I = 34000 × 0.075 × 0.273973 = 698.63115
I = $ 698.63

When the values of one variable tend to fall as the values of the other variable rise, there is a negative relationship between the two variables.

A car rental agency charges $250 per week plus $0.10 per mile to rent a car.
a. Write an equation that expresses the weekly cost to rent the car, y, in terms of the number of miles driven during the week, x.
b. How many miles did you drive during the week if the weekly cost to rent the car was $260?
Answer:
a. 250+0.10x=y
b. 250+0.10x=260
-250. -250
———————————-
0 + 0.10x = 10
——— ——-
0.10 0.10
—————————————-
X = 100
( you drove 100 miles )
Step-by-step explanation:
In question A, basically you already have a base of 250 and you add 0.10, multiplying it with x, which is the number of miles, equals to the total amount. So the answer for that question is : 250+0.10x = y. For question B, you just had to substitute the y for 260, and solve for x ( subtract 250 from both sides, divide by 0.10 on both sides, and you get x = 100. So the answer for that question is you drove 100 miles.
hope this helped =)
The cost of renting a car can be formulated as y = 250 + 0.10x, with y representing the total cost and x the distance travelled. If the total cost was $260, then 100 miles were driven.
Explanation:The car rental agency's charge can be represented as a linear equation with a fixed cost ($250/week) plus a variable cost ($0.10/mile). This can be represented algebraically as: y = 250 + 0.10x, where y is the total weekly cost and x signifies the number of miles driven.
To find out how many miles (x) were driven for a total cost of $260, substitute y with 260 in the equation and solve for x:
260 = 250 + 0.10xSubtract 250 from both sides: 10 = 0.10xDivide by 0.10 to solve for x: x = 100Therefore, if the weekly cost to rent the car was $260, you drove 100 miles.

Answer:
x = - 3.5 , y = - 5.5
Step-by-step explanation:
y = x - 2 → (1)
y = 3x + 5 → (2)
substitute y = 3x + 5 into (1)
3x + 5 = x - 2 ( subtract x from both sides )
2x + 5 = - 2 ( subtract 5 from both sides )
2x = - 7 ( divide both sides by 2 )
x = - 3.5
substitute x = - 3.5 into either of the 2 equations for y
substituting into (1)
y = x - 2 = - 3.5 - 2 = - 5.5
then x = - 3.5 and y = - 5.5
The perimeter of a rectangular red sticker is 14 millimeters. The sticker is 4 millimeters wide. How tall is it?
Answer:
3 millimeters
Step-by-step explanation:
The formula for finding perimeter: 2W+2L=P
W= width
L= length
P= Permiter
So just substitute the numbers in the equation
4 millimeters is the width
14 millimeters is the perimeter
So this is your equation
2*4+2L=14
8+2L=14
Subtract 8 from both sides
2L=6
Divide both sides by 2
L=3
So your length is 3 millimeters

b) $84000 is the total money that will be put into the account.
c) The total interest earned is obtained as $272796.54.
What is Compound Interest?
The interest that is calculated using both the principal and the interest that has accrued during the previous period is called compound interest. It differs from simple interest in that the principal is not taken into account when determining the interest for the subsequent period with simple interest. Compound interest is commonly abbreviated C.I. in mathematics.
a) Figure out the period interest rate, i.
Use the formula: i=r/m, where r is the nominal interest rate and m is the number of compounding periods.
If the bank pays 7% compounded monthly, that means that the nominal annual interest rate is 7.0% and the monthly period interest rate is 7/12 = 0.58%.
The principal amount A = $200
The number of times interest applied per time period n = 35 × 12 = 420
Now, use the uniform series compound-amount factor to find the future value.
The equation is -
F = A [((1 + i)^n) - 1] / i
where F is the future value, A is the annuity amount, i is the period interest rate.
Substitute the values into the equation -
F = 200 [((1 + 0.0058)^420) - 1] / 0.0058
F = 200 [((1.0058)^420) - 1] / 0.0058
F = 200 (11.3471 - 1) / 0.0058
F = 200 (10.3471) / 0.0058
F = 200 × 1783.9827
F = 356796.54
Therefore, the amount will be $356796.54 after 35 years.
b) The total money put in the account will be -
Total amount = The principal amount × The number of times interest applied per time period
Total amount = A × n
Substitute the values into the equation -
Total amount = 200 × 420
Total amount = 84000
Therefore, the total amount is $84000.
c) The total interest earned will be -
Total Interest = The future amount - The total money put in the account
Total Interest = F - The total money put in the account
Substitute the values into the equation -
Total Interest = 356796.54 - 84000
Total Interest = 272796.54
Therefore, the total interest is $272796.54.
