Parking in a student lot costs $2 for the first half hour and $1.75 for each hour thereafter. A partial hour is charged the same

Masteriza [31]

An easier way to think of this problem is just keep adding for each additional hour:

0.5 hours --> $2

1.5 hrs --> $3.75

2.5 hrs --> $5.50

3.5 hrs --> $7.25

and since you can only spend $7, the maximum time is 2.5 hours
