Question 10, 3.6.21-BE Part 1 of 8 O Points: 0 of 1 Save Recall that if the cost of producing x units is C(x), then the average cost function is C(x) = C(x) An artist who makes handmade earrings has fixed costs of $400 for a X table at an art fair. The marginal cost (the cost of producing one additional pair of earrings) is $7 per pair. (a) Find the linear cost function C(x). (b) Find the average cost function C(x). (c) Find C(5) and interpret your answer. (d) Find C(50) and interpret your answer. (e) Find the horizontal asymptote of C(x), and explain what it means in practical terms. (a) Find the linear cost function C(x). C(x) =
