2. Suppose rocking-chair manufacturing is a perfectly competitive industry in which there are 1,000 identical firms. Each firm's total cost is related to output per day as follows: Quantity Total cost Quantity Total cost 0 $500 5 $2,200 $1,000 6 $2,700 2 $1,300 7 $3,300 3 $1,500 8 $4.400 4 $1,800 a. Prepare a table that shows total variable cost, average total cost, and marginal cost at each level of output. b. Plot the average total cost, average variable cost, and marginal cost curves for a single firm (remember that values for marginal cost are plotted at the midpoint of the respective intervals). c. What is the firm's supply curve? How many chairs would the firm produce at prices of $350, $450, $550, and $650? (In computing quantities, assume that a firm produces a certain number of completed chairs each day; it does not produce fractions of a chair on any one day.)
