Laura rented a car that costs $20 for the day plus $.12 for each mile driven. She returned the car later that day. Laura gave the sales person $50 and received change. Which inequality represents the possible number of miles m that she could have driven?

Question

A. 50>0.12m+20
B. 50<0.12m+20
C. 50>0.12m-20
D.50<0.12m-20

I think it is D.

Thank You.

Answer 1

The answer is not D. $50 must be greater than the total cost.

If the answer were D, then this would imply that $50 is less than the total cost.

Answer 2

So is it A?

Answer 3

Yes, you are correct. $50 must be greater than the total cost of 0.12m + $20

Good job.
