Problem 1:
When the demand function is Q = 5,000 – 25P, the inverse demand function is
P = 200 – 0.04Q
TR = (P)(Q)
= 200Q – 0.04Q
2
MR = 200 – 0.08Q
TC = 1500 + 20Q + 0.02Q
2
MC = 20 + 0.04Q
Profit is maximized when MR = MC
200 – 0.08Q = 20 + 0.04Q
Or, 0.12Q = 180
Or, Q* = 180/0.12 = 1500
Therefore P* = 200 – (0.4*1500) = 200 – 60 = 140

Profit = TR – TC = 210000 – 76500 = 133500. Therefore, in the first year it will be earning a
profit of $133500.
Getting attracted by this profit other firms outside the industry will be attracted and enter
the industry. As more and more firms enter the industry, the number of products available to a
consumer will increase. The demand curve for each firm will shift to the left. Again, if the firms
were incurring losses in the short run, few firms will go out of the industry which will lower the
consumers’ choice and shift the demand curve faced by each firm to the right. This process of
entry and exit will continue till firms are earning zero profit.
