Solve the problem.An-Mei owns a business making and selling jackets. She has a fixed cost of $4050. It costs $69 to produce each jacket. The selling price is $96 per jacket. Let x represent the number of jackets produced and sold and write the cost function, C, and revenue function, R.
A. C(x) = 69x + 4050 R(x) = 96x B. C(x) = 69 + 4050x R(x) = 96 C. C(x) = 69x + 4050x R(x) = 96x D. C(x) = 69 + 96x R(x) = 4050x
