Tombstones are produced in a monopolistic competitive market. One producer, Rolling
Stones, sells 20 tombstones a week at a price of $500 each. Its average total cost is
$600. From this information, we can tell:
a. new tombstone firms will want to enter.
b. this producer is losing $2,000 a week.
c. this producer is making an economic profit of $400.
d. this producer is setting MR = MC.
e. this producer should increase production.
Suppose that when output is 20, marginal cost is $20, and average total cost is $30.
Then which of the following is most likely to be true?
a. Average total cost is declining.
b. Average total cost is constant.
c. Average total cost is rising.
d. Average total cost is less than average fixed cost.
