A trampoline park charges an hourly rate(H) to bounce, and a 15 dollar entrance fee, so even if you don't bounce on the trampolines, you still have to pay 15 dollars to get in. If you do bounce you will have a total cost (T) which includes the amount of hours bounced, and the entrance fee. Below, see the table which displays the total cost (T) to bounce, for the amount of hours(H) you choose.
The table is:
Hours (variable “H” for hours)
Total Cost (variable “T” for total cost)
$15 (just to get in)
If you stay for 1 hour its $ 25
if you stay for 2 hours its $ 35
if you stay for 3 hours its $ 45
if you stay for 4 hours its $ 55
