Grim and Mandy want to join a gym. Grim is interested in a gym that has a $200 fee to join and charges $10 per month. Mandy is interested in a gym that has a $20 fee to join and charges $40 per month. How many months will it take for the total cost that Grim and Mandy each pay to be equal?

Oh I hate math :(

Step-by-step explanation:

6 months

Step-by-step explanation:  

So the fee for one gym is 200 and the other one is 20.

so if you multiple 6 times 10 you get 60, then you add with 200 to get 260.

then, 40 times 6 gets you 240, and you add that with the $20 of the memberships fee to get 260

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
