Answer:
With 20 visits in one year the cost of the clulbs are equal.
Step-by-step explanation:
On the club A the amount paid in function of the number of visits can be expressed as bellow:
cost = 60 + 2*visits
On the club B the amount paid in function of the number of visits can be expressed as:
cost = 20 + 4*visits
In order for the cost to be the same we must find a value of visits that makes them equal, so we have:
60 + 2*visits = 20 + 4*visits
2*visits - 4*visits = 20 - 60
-2*visits = -40
visits = 20
With 20 visits in one year the cost of the clulbs are equal.
