Renee is wanting to join a gym.
Pumping iron has a $90 membership fee and is $10 a month. Fit for life has a $50 membership fee and is $15 a month.
After how many months will the two gyms cost Renee the same amount of money?
Create an equation to represent the situation. Then, solve your equation.
Set them equal to each other. 10x+90=15x+50. Solve for x. Subtract 50 from both sides, get 10x+40=15x, then subtract 10x from both sides, getting 40=5x. Divide 5 from both sides to isolate x, x=8. After 8 months the two gyms will cost the same.
