Answer:
[tex]f(x)=120+15x[/tex]
Step-by-step 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: [tex]f(x)=120+15x[/tex]
Hence a function f(x) that models the total amount of money Emerson has after x weeks is [tex]f(x)=120+15x[/tex] .
