Amelia wants to take group fitness classes at a nearby gym, but needs to start by selecting a
membership plan. With the first membership plan,
Amelia can pay $75 per month, plus $2 for each
group class she attends. Alternately, she can get
the second membership plan and pay $37 per

membership plans end up costing the same total
amount. What is that total amount? How many
classes per month is that?
