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 b
kirill [66]

Answer:

25 + 0.15m = 71.8

Step-by-step 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.
