The rental company charges $19.95, plus 17 cents for each mile driven. If Nina only has $50 to spend on the car rental, what's the maximum number of miles she can drive

Answer 1

Cost = $19.95 + $0.17(m)

m=number of miles driven

Cost cannot exceed $50

50 = 19.95 + .17(m)

Subtract 19.95 from both sides

30.05 = .17m

Divide each side by 0.17

m = 176.76

She can drive 176 miles since 177 miles would be over her budget.
