y = 20*(4) + 60
y = 80 + 60
y = $140

Who would pay less after a year of membership?
Answer:

- Tom decides to join Platinum Gym
So, after a year (12 months) of membership, Tom must pay
y = 20x + 60
y = 20*(12) + 60
y = 240 + 60
y = $300

- Edward joins Super Fit
So, after a year (12 months) of membership, Edward must pay
y = 10x + 150
y = 10*(12) + 150
y = 120 + 150
y = $270
