200+55x=50+60x
200= 50+5x
150=5x
x=30
So it will take 30 months where both gyms will be the same price.
Next question: 200+55(15)=$1,025 that is how much Sam would pay in total .
Last question :
200+55x=20+65x
200= 20+10x
180=10x
x=18
So the answer to last question is it will take 18 for both gyms to be the same cost
