Cost = 125 + 57*(Months)
Explanation:
A “Function” is a description of how one variable changes with respect to another variable.
In this case the variables are cost and time (months). The function is that the cost will equal the initial amount plus the subsequent amount for every month. This is represented algebraically as
Cost = 125 + 57*(Months).
