Question

Ms. White wants to rent a small car for a week. It will cost the weekly fee plus $0.30 per mile driven. Let m = the number of miles Ms. White drives during the week. Write an expression that shows the amount she will pay for the car. Evaluate the expression you wrote to find out how much Ms. White will pay if she drives 100 miles.

Answer 1

Note: We are not given the weekly fee, but I'll assume it as $80 only to be able to solve the problem and explain the procedure.

Answer:

Ms. White will pay $110 if she drives 100 miles

Explanation:

Ms. White wants to rent a car for a week. It costs a weekly fee of $80 plus a $0.30 fee per mile driven.

If we call m = the number of miles driven by Ms. White during the week, then the cost of renting the car is:

C(m)= 80 + 0.30m

If Ms. White drives m=100 miles during the week, then the cost is:

`C(100)= 80 + 0.30\cdot 100`

C(100)= 80 + 30

C(100)= $110

Ms. White will pay $110 if she drives 100 miles
