Answer:
29 minutes
Explanation:
Raymond's total charge is the sum of the entrance fee and the per-minute charge for the number of minutes he used the trampoline:
total charge = entrance fee + (per minute charge) × t
43.25 = 7.00 + 1.25t . . . . . filling in the given numbers
36.25 = 1.25t . . . . . . . . . . . subtract 7
t = 36.25/1.25 = 29 . . . . . . divide by the coefficient of t
Raymond was on the trampoline for 29 minutes.
