Question

Maggie has $32 in her money box. She plans to put $9 in her money box every month. If f(n) represents the total amount of money Maggie will have in her money box after n months, which of the following functions represents the relationship between f(n) and n?

f(n) = 9n + 32

f(n) = 32n + 9

f(n) = 41n + 9

f(n) = 9n + 41

Answer 1

I think it's the first

Answer 2

`So she get $9 each month (n)`,
We can write this as 9 times n.

She has $32 at the very start, or when n=0.
f(0)=32

Mmmm yah looks like you've got it :)
