Question 644655: tialParking in a student lot costs $3 for the first half and $1.25 for each hour thereafter. A partial hour is charged the same as a full hour. What is the longest time that a student can park in the lot for $8?
I have to show how this problem is solved, and don't even know where to start other than I think it should start as an equation to figure out the number of hours. Thank you.

--------
You need an equation relating time and cost.
----
cost = 1st hr cost + 1.25*(# of additional hours)
----
C = 3 + 1.25x

You need to solve for time.
8 = 3 + 1.25x
1.25x = 5
x = 4 hrs.
