Suppose that single-price, single-product and single-plant monopolist faces the following demand curve: Q $5,000 and its average variable cost is 0.01Q. Find the profit of the monopolist. = 5000 25P. The monopolist's fixed cost of production is O $190,000 O $195,000 $182,500 $200,000

Assuming that the price is greater than the average variable cost, a monopolist maximizes profits at the output for which (picture a graph): O price is equal to marginal revenue in the downward part of the marginal cost curve O marginal cost is equal to marginal revenue in the upward sloping part of the marginal cost curve O average variable cost and average total cost are in the downward part of their curves and price is equal to marginal cost O average total cost is at the lowest point

Exhibit 10-4 $/0 MC ATC 24 /t 10 The non-discriminating monopolist in Exhibit 10-4 should: O Produce 10 units at a price of $36 per unit. O Produce 10 units at a price of $24 per unit. O Produce 10 units at a price of $40 per unit. O Produce 15 units at a price of $32 per unit. O We cannot determine what the firm should do without knowing its average variable cost.

Please help

A single-price monopolist is currently producing at an output level where marginal revenue is $14, marginal cost is $16, AVC=$13, and ATC= $15. It is assumed that the monopolist, as usual, chooses its price on the demand curve. To maximize profit or minimize losses in the short run, this monopolist should O A. decrease the price and increase the level of output. O B. increase the price and the level of output. O C. leave the market. O D. decrease the price and the level of output. O E. increase the price and decrease the level of output.

The quantity sold by a monopolist using first degree price discrimination is higher than the quantity sold by a monopolist who cannot price discriminate. O True O False

If a monopolist with significant barriers to entry is making positive economic profit in the short run, what do we expect to happen as the market transitions to the long run? O The profit will increase since the monopolist has no competition, they can just raise the price to earn higher profits. O It will decrease as positive economic profit signals new firms to enter the market, increasing the market supply, and lowering the prevailing price. O It will increase, in the long run firms will drop out the market increasing the monopolists dominance in the marketplace. O The profit will stay the same, strong barriers to entry prevent new competition.

QUESTION 23 If the monopolist shown in the following figure could practice first-degree price discrimination, the producer surplus would be: Price (dollars) 50 40 30 20 10 $0. $225. $450. $900. O $1,200. 30 50 60 MR 100 MC Quantity

Question 30 Demand: P=120-Q Marginal Revenue: MR=120-2Q Total Cost: TC=Q² Marginal Cost: MC=2Q For this monopolist, the profit-maximizing price is and the profit-maximizing quantity is 90, 30 30, 90 40, 80 None of these answers O O O

If a monopolist faces an inverse demand curve, p(y) = 100-2y and has constant marginal costs of $32 and zero fixed costs and if this monopolist is able to practice perfect price discrimination, its total profits will be O a. $1,156. O b. $17. O c. $578. O d. $1,734. O e. $289.
