what are the miles

Question

Sydney needs to rent a car while on vacation. The rental company charges $18.95, plus 18 cents for each mile driven. If Sydney only has $50 to spend on the car rental, what is the maximum number of miles she can drive?

Answer 1

50 = 18.95 + .18M

.18M = 50-18.95

M = 31.05/.18

M = 172.5 miles on $50 if charges are $18.95 + 18 cents per Mile

172.5(.18) = 31.05

31.05 + 18.95 = $50

if they charge for a full mile for any part of a mile then 172 miles is the maximum possible
