It costs $300 to join the new Superfit Gym. You then pay $15 each month and $2 each time you work out. Carlo thinks he will use the gym about 20 times each month for a year. Part A : Write An Expression You can use to calculate the cost of SuperFit Gym For One Year. Part B : Use Your Expression to calculate the cost of using the SuperFit Gym for one year.
