Ashton works as a marketing manager for a consumer products firm. His total earnings, A, in x months is given by the function A(x) = 2,400x + 40x2. His total savings, S, in x months is given by the function S(x) = 250x + 500.



The function E(x) = 40x^2 + 2,150x - 500 40x^2 + 2,650x + 500 40x^2 + 2,150x + 500 40x^2 + 2,650x - 500 represents Ashton’s total expenses in x months.

Ashton’s expenses for 3 years total $ 6,310 8,810 128,740 147,740 .

E(x) = A(x) - S(x) = 2400x + 40x^2 - (250x + 500) = 2400x + 40x^2 - 250x - 500 = 40x^2 + 2150x - 500

Ashton's expenses for 3 years E(3) = 40(3)^2 + 2150(3) - 500 = 40(9) + 6450 - 500 = 360 + 5950 = $6,310

Answer:

So the answers are 40^2+2,150x-500 and $128,740
