RetroFitness and NY Sportsclub are two gyms in the tri-state area that are being sponsored by the local newspapers. There was a study that was done to see the growth of both gyms based on x, the number of years the gym has been opened, and y, the number of members within the gym. The equations to represent
the number of members based on number of years opened for each gym is shown below.
RetroFitness: y = 90x+ 200
NY Sportsclub: y = 100x + 100
