Charles's Math Tutoring
Suppose that Charles's math tutoring company has a fixed cost of $50 per month for his
cell phone. Each worker costs Charles $60 per day. As output increases from 45 to 70
students, Charles's total cost curve
a.increases but gets flatter.
b.increases and gets steeper.
c.decreases and gets flatter.
d.decreases but gets steeper.
6) Suppose a profit-maximizing monopolist faces a constant marginal cost of $10,
produces an output level of 100 units, and charges a price of $50. The socially efficient
level of output is 200 units. Assume that the demand curve and marginal revenue curve
are the typical downward-sloping straight lines. The monopoly deadweight loss equals
$2,000.
a.True
b.False

statements is correct?
a.The firm is earning a positive short-run profit.
b.The firm is earning a negative short-run profit.
c.The firm is earning zero short-run profit.
