Emerson has $120. Each week he saves an additional $15. Write a function f(x) that models the total amount
of money Emerson has after x weeks.
Since Emerson is adding 15x to the $120 that he currently has, then: f(x) = 120 + 15x {total, f(x), equals adding 15 per week to the original 120} Ask Algebra House Comments are closed.
