Consider the following table showing the various revenue concepts for DairyTreat Inc., a perfectly competitive firm that sells milk by the litre. Suppose the firm faces a constant market price of $2 per litre.

a. Compute total revenue for each level of output. Fill in the table.
b. Compute average and marginal revenue for each level of output. Fill in the table. (Remember to compute marginal revenue between successive levels of output.)
c. Explain why for a perfectly competitive firm, AR = MR=p.
d. Plot the TR, MR, and AR curves on a scale diagram. What is the slope of the TR curve?
