Colton is becoming a member at a community swimming club. It costs $20 per month and $40 up-front to join the club. Which equation shows when the average cost per month (m) of joining the swimming club will be $30? A,30=40m+20m B.30=20m+40m C.30=20m+40 or D.30=40m+20 pls help
The $40 is a one-time payment, so it is represented by 40. The $20 is a monthly payment, so it is represented by 20m. So the right equation would be 30 = 20m + 40.
