A parking garage charges $2.71 for the first hour and $0.50 for each additional hour or part of an hour. What is the maximum length of time he can park in the garage if he wishes to pay no more then $7.71?

What maximum length of time in hours can park

Jul 8th, 2014

7.71 = 2.71 + .5x

5.5 = .5x

11 = x

Thus, the max length is 12 hours (i.e., the first hour for $2.71, then 11 more hours for an additional $5.50)
