The total cost is $43.24.
We know that there is a $7.00 entrance fee so we can go ahead and subtract 7 from 43.24
43.24 - 7 = 36.24
We know that the rest of the price is the minutes that Raymond was on the trampoline. So what we will do is divide 1.25 from 36.24
36.24 ÷ 1.25 = 28.992
We will round up 28.992 to 29.00
so we can say that Raymond was jumping on the trampoline for about 30 minutes for a total of $43.24.
