(not shown) C.) Find the marginal average cost function and the marginal avsrage cost at x=40 and x=80

8x + 1 N Bri G The Student Government Association is making Mother's Day gift baskets to sell at a fundraiser. If the SGA makes a larger quantity of baskets, it can purchase CH materials in bulk. The total cost (in hundreds of dollars) of making x gift baskets can be approximated by C(x) - X+ 80 Complete parts (a) through (c) below. (a) Find the marginal cost function and the marginal costat x 40 and x = 80, Lee The marginal cost function is The marginal cost at x = 40 is $ (basket. (Round to the nearest cent as needed.) The marginal costat x = 80 is s basket, Fog Go (Round to the nearest cent as needed) (b) Find the average-cost function and the average cost at x 40 and x = 80 The average-cost function is The average cost at x 40 is basket (Round to the nearest cent as needed) Enter your answer in each of the answer boxes
