Question

In order to become a member at the local gym, there is a $50 startup fee, then a $20 fee every month. Write an equation that models this situation where c, the total cost, is a function of g, the number of months spent at the .

Answer 1

c=20g+50

Explanation:

The format of this equation is y=mx+b, where m is the slope and y is the y-intercept.

The $20 monthly would signify the slope because it is added to the account each month.

The $50 would signify the y-intercept because it is the amount that stays constant since it is a startup fee.

Answer 2

c = 20g+50

Explanation:

We can use the slope intercept form

c = mg+b where m is the change and b is the starting amount

m = 20

b = 50

c = 20g+50
