Best ResponseYou've already chosen the best response.0m + 5f = 25 m + 10f = 40 m = 25  5f (25  5f) + 10f = 40 etc

Best ResponseYou've already chosen the best response.0(25  5f) + 10f = 40 So then I solve this by subracting 5f from both sides right?

Best ResponseYou've already chosen the best response.0let x be the total monthly fee let y be the cost per session Then we can get x+5y=25 x=255y Again, x+10y=40 Now, we can substitute the value of x and solve for y 255y+10y=40 5y=4025 y=15/5=3 Now , we can find x by using one of the above eq x=255(3) x=10 Thus the total monthly fee is 10$ and the fees per session is 3$
