parking in a student lot costs $1 for the first half hour and $1.25 for each hour there after. a partial hour is charged the same as a full hour what is the longest time that a student can park in this lot for $7?
$! for the first half-hour
$6 remain to cover the remaining time.
6/1.25 = ?
Don't forget to add the half-hour above.
