Question

The cost to rent a car is $25 plus an additional $0.15 for each mile the car is driven. Which of the following equations could be used to find the number of miles, m, a car was driven if the car had a bill of $71.80?

25m + 0.15 = 71.8
71.8m + 25 = 0.15
25 + 0.15m = 71.8
0.15m + 71.8 = 25

Answer 1

25 + 0.15m = 71.8

Explanation:

Given:

Fixed charge = $25

Additional charge for each mile = $0.15

Let number of miles driven be m.

Total Billed amount = $71.80

Now total bill amount is calculated by adding fixed charge with additional charge for each mile times number of miles.

Hence,

Total Billed amount = Fixed charge + Additional charge for each mile × number of miles driven

25 + 0.15m = 71.8

Hence the equation is 25 + 0.15m = 71.8.
