Question

julie opens a bank account with $500.she deposits $60 each month.write a function that represents the amount that is in julies account after x months

Answer 1

`f(x) = 500 + 60x`

Explanation:

Given

`Ope\ ning\ Balance = 500`

`Deposits = 60` --- monthly

Required

Write as a function

Represent the number of months with x and the balance at any month with f(x)

f(x) is calculated as thus:

Opening Balance + Deposits * Number of Months

So, we have:

`f(x) = 500 + 60 * x`

`f(x) = 500 + 60x`

Hence, the function that represents the scenario is

`f(x) = 500 + 60x`
