For 12 months, Janenne has belonged to a book-of-the-month-club. Janenne has spent 70.45 on the club. The first month, she payed a monthly fee and spent an additional 10.45 on books. She has only payed the monthly fee since then. What is the initial values of the rate of change of the function

The rate of change of the function = 5

Step-by-step explanation:

From the given parameters, we have;

The number of months Janenne has belonged to the book-of-the-month-club = 12

The amount Janenne has spent on the club = 70.45

The amount she paid in the first month = Monthly fee + 10.45

Let the monthly fee = x

The total amount Janenne has spent on the club  can be given by the following formula;

10.45 + 12×x = 70.45

12×x = 70.45 - 10.45 = 60

x = 60/12 = 5

The monthly due of the book club = 5

Therefore, the rate of change of the function × 5

The function of the amount spent on the club = Y = t×x

Where;

x = The rate of change of the function

t = The time in months

The rate of change of the function = 5.
