Question 977196: A hospital parking lot charges $1.50 for the first hour or part thereof, and $1.o for each additional hour or part thereof. A weekly pass costs $27.00 and allows unlimited parking for 7 days. Suppose that each visit Hailey makes to the hospital lasts 1 1/2hr. What is the minimum number of times that Hailey would have to visit per week to make it worthwhile for her to buy the pass?

How much will each visit cost Hailey? $1.50 for the first hour and an additional dollar for the portion of the second hour.
Each visit costs her $2.50
$27 / $2.50 = 10.8
Therefore, she loses money by buying the weekly pass if she visits fewer than eleven times (round up, since she's not visiting a portion of a time).
Pay as she goes if ten or fewer; buy the pass is eleven or more.

Each visit costs $2.50 to park, $1.50 for the first hour and $1 for the second half hour, since that is part of an hour.
Unlimited passes cost $27 a week.
$2.50x>=$27
x.>=10.8 times or at least 11 visits weekly to make buying the pass worthwhile
At 14 visits per week, she would save money.
