Answer:


f(x)=120+15x

Explanation:

Given : Emerson has $120

Each week, he saves an additional $15.

To Find: Write a function f(x) that models the total amount of money Emerson has after x weeks.

Solution:

He saves in 1 week = $15

He saves in x weeks = $15x

He already has $120

So, total amount of money = 120+12x

So, Function:
f(x)=120+15x

Hence a function f(x) that models the total amount of money Emerson has after x weeks is
f(x)=120+15x .
