Answer:
B. Lower its price to $14.
Step-by-step explanation:
Price Quantity Total Cost TR MR MC
$22 0 $20 - -
20 1 24 20 20 4
18 2 27 36 16 3
16 3 33 48 12 6
14 4 40 56 8 7
12 5 49 60 4 9
10 6 59 60 0 10
A pure monopolist maximizes profit at the point where marginal cost (MC) is equal to the marginal revenue (MR)
Therefore, in order to maximize profit the firm should lower its price to $14 because that is the only point where the MR of $8 is the closet to the MC of $7.
