Answer: Step-by-step explanation: Assuming that for each option, you play the same number of games,x Let y represent the cost of playing x games using option A Option A is to buy a membership card and pay $2 every time you go to the gym. The membership card costs $20. It means that y = 20 + 2x Let z represent the cost of playing x games using option B Option B is to pay $4 each time you go. It means that z = 4x To determine how many games will be played before cost of option A equal to the cost of option B, we would equate y to z. It becomes 20 + 2x = 4x 4x - 2x = 20 2x = 20 x = 20/2 = 10 It will take 10 games for both to be the same
