If A (x) is his total earnings and S (x) is his total savings, his total expenses is the difference between his total earnings and total savings.

A (x) = 2400x + 40x^2

S (x) = 250x + 500

let E (x) be the total expenses:

E (x) = A (x) - S (x)

E (x) = 2400x + 40x^2 - (250x + 500)

E (x) = 40x^2 + 2150x - 500
