Mr. Junaid produces Led TV for sale, which requires a building and a machine that can help them to produce Led TVs. Junaid rents a building for 30,000 per month and rents a machine for 20,000 a month. Those are his fixed costs. His variable cost per month is given in the accompanying table.

Quantity of TV 1000 2000 3000 4000 5000 6000 7000 8000 9000 10000

a. Calculate Junaid's average variable cost, average total cost, and marginal cost for each quantity of output.

b. There is free entry into the industry, and anyone who enters will face the same costs as Junaid. Suppose that currently the price of a TV is $25. What will Junaid's profit be?
