Assume the following demand curve: Q = 50,400 – 1,200(P). Variable costs are estimated to be $25.10

Assume the following demand curve: Q = 50,400 – 1,200(P). Variable costs are estimated to be $25.10. Calculate total contribution margin at the optimal price. Round your answer to the nearest dollar.

5 - Assume the following demand equation: Q = 729 - 21(P). Variable costs = $6. Calculate marginal revenue for the 251st unit. Round your final answer to the nearest dollar.

(When you are calculating the two prices, do not round to less than 2 decimal places. In other words, you are safe to round each price to the nearest penny.)

Assume a consumer whose demand curve is given by p = 10 – q. There is an incumbent monopolist whose marginal cost is 2. What are the monopoly price, monopoly profit, and consumer surplus? Now suppose that there is a potential entrant whose marginal cost is zero. If there is entry, the incumbent firm and the entrant compete in prices for the homogenous product. If entry, what would be the market price and what would be consumer surplus? Can the...

The market demand curve is P = 260 – Q, where Q is the output of Firm 1 and Firm 2, q1 + q2. The products of the two firms are identical. a. Firm 1 and Firm 2 have the same cost structure: AC = MC = $20. If the firms are in a competitive duopoly, how much profit does each firm earn? b. Now suppose that Firm 2's production costs increase to AC = MC = $80. If the...
