# The health club charges joining fee of 125 plus $57 per month, how do you write a function?

Cost = 125 + 57*(Months)

An explanation of how one variable changes in relation to another is called a "function."

The variables in this instance are time (months) and cost. The function is that each month's cost will equal the starting amount plus the amount that comes after it. This can be expressed algebraically as follows: Cost = 125 + 57*(Months).
