the charge for a one-day rental of a car from Shurtz Car Rental Agency is $24 plus 15 cents for each mile driven. a.) If Jill drives 85 mi in one day, how much is the charge? b.) If a one-day rental cost Jill $42, how far did she drive? please answer it.

Total cost = Standard charge + .15 x total miles driven

Jill's total cost = 24 + .15(85) = 24 + 12.75 = $highlight_green%2836.75%29

42 = 24 + .15(M), with M being the amount of miles driven on that day

42 = 24 + .15M

42 - 24 = .15M

18 = .15M

M, or miles driven = 18%2F.15 = highlight_green%28120%29
