Accepted Solution

A:
Answer:B: after 5 monthsStep-by-step explanation:Make to equations from the given informationLet y be the cost, and let x be the number of monthsGym 1:  y = 35.65x + 75Gym 2:  y = 17.95x + 164It wants to know when the cost will be the same, so set the 2 equations equal to each other and solve..35.65x + 75 = 17.95x + 16417.70x = 89              (subtract 17.95x and 75 from both sides)   x = 5.02                (divide both sides by 17.7)So after 5.02 months the cost will be equal, since 5.02 is greater than 5 months, the answer is after 5 months, which is B
