Answer 1

Answer:

Equation which could be used to find the number of miles, m, a car was driven if the car had a bill of $71.80 is:

71.50=25+ 0.15m

Step-by-step explanation:

The cost to rent a car is $25 plus an additional $0.15 for each mile the car is driven.

Let m be the number of miles a car was driven.

Car had a bill of $71.80

⇒ 71.50=25+ 0.15m

0.15m=71.50-25

0.15m=46.5

⇒ m=46.5/0.15

⇒ m=310

Hence, equation which could be used to find the number of miles, m, a car was driven if the car had a bill of $71.80 is:

71.50=25+ 0.15m

and number of miles it was driven=310

Answer 2

71.80 = .15m+25
-25. -25
56.80=.15m
____ ___
.15. .15

m = 378.66666667

378.667 Miles
