12) Currently, a monopolist's profit-maximizing output is 300 unit per week. It sells its output @ a price of $55 per unit and collect $35 per unit in revenues from the sale of the last unit produced each week. The firm's total costs each week are?--------
13) The following table shows demand a d marginal cost for a monopolist. Calculate marginal revenue at each quantity.
output (units) price per unit marginal revenue marginal cost
0 56 ---- -------

2 35 20
3 25 30
4 15 40
5 5 50
8) Suppose that a perfectly competitive firm faces a market price of $7 per unit and @ this price the upward-sloping portion of the firms marginal cost curve crosses its marginal revenue curve at an output level of 1,400 units, its average variable costs equal $6.50 per unit , and its average fixed cost equal $0.80 per unit. What is the firm's profit-maximizing ( or loss minimizing ) output level? ( include minus sign if necessary.)
9) The following table shows marginal and avg. total cost schedules for a perfectly competitive firm. Currently, the market price in this industry is $40. output (units) marginal cost avg. total cost
0 -------- --------
1 10 35
2 20 28
3 30 18
4 40 31

A profit - maximizing firm will produce ------- units
14) Currently, a monopolist's profit- maximizing output is 250 units per week. It sells its output @ a price of$70 per unit and collects $40 per unit in revenues from the sale of the last unit produced each week. The firms total costs each week are &8,500. Given this information, the firm's maximized weekly economic profits are $______________.
21) Suppose that the distribution of sales within an industry is as shown in the following table:

2) At the end of the year, a firm produced 18,000 lab top computers. Its total costs were $8 million , and its fixed costs were $5 million. what are the avg. variable costs of this firm?
c $80,00,000.00
Fixed Cost $50,00,000.00
Total Variable cost $30,00,000.00 Note: Total Variable ost = Total Cost - Fixed Cost
No of laptops produced 18,000
Average variable cost $166.67 Note: Average variable cost = Total variable ost / Number of units produce
