Use the following information for a monopoly firm to answer questions 27 through 29. Assume that Q equals the level of output and all costs are economic costs. 

Total Revenue = 250Q - 0.5(Q squared)

Marginal Revenue = 250 - Q

Total cost = 2,000 + 50Q + 0.5(Q squared)

Marginal cost = 50 + Q

27. At the profit-maximizing or loss-minimizing output level, economic profit would equal:

$5,000.

$8,000

$9,000.

$19,000.

]

28.Under these conditions, the firm should produce an output of:

zero (i.e. shutdown).

100.

200.

None of the above.

29. At an output of 200 units, total costs equal:

$20,000.

$28,000.

$29,000.

$32,000.
