A hospital parking lot charges 2.00 for the first hour or part thereof, and $1.00 for each additional hour or part thereof....?
A weekly pass costs $39.00 and allows unlimited parking for 7 days. If each visit Jonny makes to the hospital lasts two and a half hours,
what is the minimum number of visits for which buying a pass would be less expensive than paying each time?

For each visit, Jonny has to pay $2+$1+$1=$4. Let Jonny would pay
n visits in a week, then
4n>39=>
n>9.75=>
n=10
Ans. the min. number of visits in a week
should be 10 times.
Parking for each 2½-hour visit costs $4
39/4 = 9.75
If he makes 10 visits in a week, the weekly pass is less expensive.
