Find a rule for the function.Using the function from the previous question, find the cost of using the gym for 9 months.

Answer 1

the initial membership fee never changes. as months pass, it remains the same one-time payment.

if x are months, do you think the one-time payment should be multiplied with x?

Answer 2

yes... so it would be, C = 28m + 127?
