Question

1. Consider a monolopy where the inverse demand for its product is given by P = 50-2Q. Total costs for this monopolist are estimnated to be C(Q) = 100 + 2Q + Q^2. At the Profit-maximizing combination of output and price, consumer surplus is?

Answer: $64

2. You are the manager of a firm that sells its product in a competitive market at a price of $48. Your firm's cost function is C = 60+2Q^2. Your firm's maximum profits are

Answer: $228

I already know the answers, please show how it works! Thank you!!

Explanation / Answer

1) P=50 -2Q


R = 50Q - 2Q^2


MR = 50 - 4Q


C = 100 +2Q + Q^2


MC = 2+2Q


when MR = MC


50 - 4Q = 2+2q


6Q = 48


Q = 8 units


P = 50 -16 = 34


consumer surplus = (50-34) * 8/ 2 =64


2) in competativemarket firm earns maximum profit when MC =P


C = 60 + 2Q^2


MC = 4Q


4Q = 48


Q = 48/4 = 12


profit = 48 * 12 - (60+ 2* 12^2)


=228
