$40 + $7.50x = $12.50x, then combine the terms 7.5 and 12.5. 40 = 5x x = 8 So if a member and a nonmember rent boats 8 times, they would have to pay the same price.
A member and a nonmember would need to rent a boat 8 times for their total costs to be equal, with the member having a fixed membership fee and a lower rental rate. The equations are set up to show how total cost changes with the number of rentals. By solving these equations, we find the point of equality.
