Refer to Exhibit 2. A single-price monopolist that seeks to maximize profits will sell __________ units and charge a per-unit price of __________. Group of answer choices

20; $9

40; $7

50; $6

10; $10

7; $40

Answer 1

Answer-B 40; $ 7

A single-price monopolist that seeks to maximize profits will sell 40 or 30 units and charge a per-unit price of $ 7 or $ 8.

But as per given group choices answer is 40 units and $ 7.

When the result of total revenue-total cost is maximum, the profit is maximized.

When 40 units will be sold at $ 7

Given Total cost= $ 170

Total revenue= Price*output sold =7*40=280

Profit=total revenue - total cost

Profit= 280-170= $ 110

Option A

If price=$9 and output=20

Given, total cost= 100

Total revenue= 9*20=180

Profit=180-100 =$ 80

Option C

If price=6 and output=50

Given, Total cost= 230

Profit= 300-230= $ 70

Option D

If price=10 and output= 10

Given, Total cost= 80

Profit= 100-80= $ 20

Option E

If price= 40 and output=7

Total revenue= 280

This quantity of output, price and cost are not mentioned in question. There is no information about cost, thus the profit cannot be determined.
