Question

Jenna just got done jumping at the Trampoline center. The total cost of the session was $15.23 She had to pay an entrance fee of $7.25 and $1.45 for every minute she was on the trampoline.

Answer 1

Answer: 5.5 minutes

Explanation:

Your question is not complete but I guess they you want to calculate the number of minutes that Jenne was on the trampoline.

Let the number of minutes be represented by m.

Therefore, based in the information, we can form an equation which will be:

7.25 + (1.45 × m) = 15.23

7.25 + 1.45m = 15.23

1.45m = 15.23 - 7.25

1.45m = 7.98

m = 7.98/1.45

m = 5.50

Therefore, Jenna used 5.5 minutes
