Question

Jamier's Trampoline Park charges $9 to get in and $4 an hour to jump. Alondra's Trampoline Park does not charge a fee to get in, but charges $7 an hour to jump? How many hoursmust you jump in order for the cost to be the same?

Answer 1

9+4x = 7x;

9 = 7x-4x;

9 = 3x;

x = 3;

So you need to be there 3 hours to achieve the same cost;
