Question

How many cars and SUVs leave to wash to make $750.00 if a car is $55.00 and an SUV is $70.00?

a) 10 cars and 5 SUVs
b) 11 cars and 5 SUVs
c) 12 cars and 8 SUVs
d) 13 cars and 9 SUVs

Answer 1

To make $750.00, there is no combination of cars and SUVs that satisfy the equation.

Step-by-step explanation:

To find out how many cars and SUVs are needed to make $750.00, we can set up a system of equations. Let x represent the number of cars and y represent the number of SUVs. The total amount made is the sum of the amount made from cars and SUVs, which is $750.00. So we have the equation 55x + 70y = 750.

There are a few combinations of cars and SUVs that would satisfy this equation:

a) 10 cars and 5 SUVs: 55(10) + 70(5) = 550 + 350 = 900 (not equal to $750.00)

b) 11 cars and 5 SUVs: 55(11) + 70(5) = 605 + 350 = 955 (not equal to $750.00)

c) 12 cars and 8 SUVs: 55(12) + 70(8) = 660 + 560 = 1220 (not equal to $750.00)

d) 13 cars and 9 SUVs: 55(13) + 70(9) = 715 + 630 = 1345 (not equal to $750.00)

There are no combinations that satisfy the equation, so none of the given options is correct.
