You can
put this solution on YOUR website!Let x the number of visits to the park
If you pay the pass you will pay 120+7x
if you do not pay the pass you will pay (32+10)x=42x
so you have to decide buy the pass if 120+7x<42x
then 120<35x then 24<7x
then x>3
R:you have to buy the pass if you are going to do more than 3 visits to the park
