Question

When would Casey pay the same amount to be a member of either gym? How much would he pay?

Answer 1

Answer: After 6 Months Casey would have paid $450 at either gym.

Step-by-step explanation:

Since we're looking for these two gyms cost the same, we need to make the equation compare the two together:

35x + 240 = 75x (the 1st gym with a joining fee $240 and 35 monthly equals $75 monthly)

Subtract 35x from both sides:

35x - 35x + 240 = 75x - 35x

240 = 40x

Divide by 40:

240 / 40 = 6

6 = x

So they cost the same after 6 months

35 * 6+ 240 = 75 * 6

450 = 450

And you'll be spending $450 in total.
