11. Problems and Applications Q11
Suppose that each firm in a competitive industry has the following costs:
Total Cost: TC = 50 +
Marginal Cost: MC = q
The market demand curve for this product is:
Demand
where P is the Price and Q is the total quantity of the good..
What is each firm's variable cost?
0.5q
50+0.5q
q
Which of the following represents the equation for each firm's average total cost?
50q
50+0.5q
0.5q
Complete the following table by computing the marginal cost and average total cost for qq from 5 to 15.

The average total cost is at its minimum when the quantity each firm produces (q) equals ____________.
Which of the following represents the equation for each firm's supply curve in the short run?
50−q
120−0.5
0.5
q
In the long run, the firm will remain in the market and produce if _________.
Answer 1. Variable cost=0.5q^2
Reason- Variable cost depends on quantity.
Answer 2. Average Total cost=50/q+0.5q
Reason- Average total cost= Total cost/ Quantity= (50+0.5q^2)/q= 50/q+0.5q
Answer 3.
q | MC=q | ATC=50/q+0.5q |
5 | 5 | 12.5 |
6 | 6 | 11.8 |
7 | 7 | 10.6 |
8 | 8 | 10.2 |
9 | 9 | 10.05 |
10 | 10 | 10 |
11 | 11 | 10.04 |
12 | 12 | 10.16 |
13 | 13 | 10.3 |
14 | 14 | 10.5 |
15 | 15 | 10.8 |
Answer 4. ATC is minimum when Q=10.
Answer 5. q
Reason- MC is the short run supply curve above the price level.
Answer 6. In the long run firm will remain in the market and produce if q≥10.
As As q=10, ATC is minimum.
