A video game store adds a 25% markup on each of the games that it sells. In addition to the manufacturer's cost, the store also pays a $1.50 shipping charge on each game.
Answers
Answer:
[tex]y=1.25x+1.5[/tex]
Step-by-step explanation:
Step one:
given data
let the manufacturing cost of the video game be x
25% of x
=25/100*x
=0.25x
the new price of the video game will be
=0.25x+x
=$1.25x
cost of shipping is given as $1.5
let the total cost of producing a video game be y
The expression for the total cost of one video game is given as
[tex]y=1.25x+1.5[/tex]
Shipping Company A charges $14 plus $2.25 a pound to ship overnight packages. Shipping Company B charges $20 plus $1.50 a pound to
ship an overnight package. For what weight is the charge the same for the two companies?
Let p represent the number of pounds. Select the correct values to write an equation to represent the situation
Answers
Answer:
8 pounds
Step-by-step explanation:
Shipping Company A = 14 + 2.25p
Shipping Company B = 20 + 1.50p
Where,
p = the number of pounds.
For what weight is the charge the same for the two companies
Equate the charges of the two companies
14 + 2.25p = 20 + 1.50p
14 - 20 = 1.50p - 2.25p
-6 = -0.75p
Divide both sides by -0.75
p = -6 / -0.75
= 8
p = 8 pounds
Seth's father is thinking of buying his son a summer movie pass for $30 dollars. With the pass, matiness cost $4 each.
Without the pass each movie is normally $8. If Seth plans to go to 30 movies this summer how much money would he
save?
Answers
Answer:
Seth saved $90.
Step-by-step explanation:
1.Find out how much would be spent without buying the movie pass.
Multiply the amount of money that one would spend for each movie, by the number of movies one saw.
8 * 30 = 240
2.Find out the amount that was actually spent
Multiply the amount that was actually spent on each movie, by the number of movies that were seen. Then add the additional cost of the pass.
(4 * 30) + 30
= 120 + 30
= 150
3. Find the difference between the two values.
Subtract the amount that one was supposed to spend by the amount one did spend.
240 - 150
= 90

f(x)= 4x-5 what is f(100)?
Answers
Answer:

Step-by-step explanation:
f ( x ) = 4x - 5
f ( x ) = Y-value
x = x - value
If f ( 100 ) = The Y is 100
100 = 4x - 5
+5 = +5 Add 5 on both sides. The 5's will cancel on the right

Explain how to determine whether a product(answer to a multiplication problem) will be positive or negative. Write in complete sentences
Answers
Answer:
when the signs of the two numbers being multiplied are the same, the product answer would be positive.And when the signs of the two numbers being multiplied are different, the product answer would be negative.Step-by-step explanation:
Whether a prdocut will be positive or negative really depends on the signs of the two numbers being multiplied.
In other words,
when the signs of the two numbers being multiplied are the same, the product answer would be positive.(positive number) × (positive number) = positive number
(negative number) × (negative number) = positive number
For example, when we multiply the positive numbers 3 and 4, the product will be positive.
i.e. 3 × 4 = 12
Also, when we multiply the negative numbers 3 and 4, the product will again be positive.
i.e. (-3) × (-4) = 12
And when the signs of the two numbers being multiplied are different, the product answer would be negative.(positive number) × (negative number) = negative number
For example, when we multiply the positive number 3 and negative number -4, the product will be negative.
i.e. (3) × (-4) = -12
I hope your concept is clear now.

A blender was originally sold for $90 and has been marked
down to $79.20. What is the percentage of discount for the
blender?
Answers
Answer:
88%
Step-by-step explanation:
From the question given above, the following data were obtained:
Original amount = $ 90
Discounted amount = $ 79.20
Percentage of discount =?
Let the percentage of discount be y %
Thus, we can obtain the value of y as follow:
y /100 × 90 = 79.20
90y /100 = 79.20
Cross multiply
90y = 100 × 79.20
90y = 7920
Divide both side by 90
y = 7920/90
y = 88
Thus, the percentage discount of the blender is 88%

Step-by-step explanation:
First, you are going to convert dollars to cents. Since there are 100 cents in a dollar, multiple $20 by 100. Now you should have 2,000 cents. Now all you have to do is divide by 19, the cost of the stamps, and you should get 105.26. Because you can't by part of a stamp your answer would be 105.

Answers
9514 1404 393
Answer:
8-ounce jar is a better buy$0.08Step-by-step explanation:
The price per ounce for the 8-ounce jar is ...
price/ounces = $8.95/8 = $1.11875 ≈ $1.12 . . . per ounce
The price per ounce for the 10-ounce jar is ...
$12.00/10 = $1.20 . . . per ounce
The 8-ounce jar has a lower unit price, so may be better to buy.*
__
The difference in unit prices is ...
$1.20 -1.12 = $0.08
_____
* If you need at most 10 ounces, but more than 8, the 10-ounce jar will have a lower total cost for the amount needed. The "better buy" depends on the context.

Answers
Answer:
(2,0)
Step-by-step explanation:
I will solve your system by substitution.
(You can also solve this system by elimination.)
2x+y=4; x−y=2
Step: Solve 2x+y = 4 for y:
2x + y + −2x = 4 + −2x (Add -2x to both sides)
y = −2x+4
Step: Substitute −2x+4 for y in x−y=2:
x − y=2
x−(−2x + 4)=2
3x − 4=2(Simplify both sides of the equation)
3x − 4 + 4 = 2+4 (Add 4 to both sides)
3x =6
(Divide both sides by 3)
x=2
Step: Substitute2forxiny=−2x+4:
y= −2x + 4
y=(−2)(2) + 4
y=0 (Simplify both sides of the equation)

x=2 and y=0
