Suppose you have three producers of oil A, B, and C, with extractions costs of $8, $10, and $12 per barrel of oil. Assume there are no user costs. Assume that each well can produce 100 barrels of oil per day. How much oil will be produced if the market price of oil is $9 per barrel?

From the information given in the question, producer A will be only producer that can produced the oil if oil market price is $9/barrel as producer B and C will not cover the extraction cost at this price. Hence, only 100 barrel oil is produced

Explanation:

Given data:

Extraction cost of oil producer A = $8

Extraction cost of oil producer B = $10

Extraction cost of oil producer C = $12

Total production of oil per day = 100

From the information given in the question, producer A will be only producer that can produced the oil if oil market price is $9/barrel as producer B and C will not cover the extraction cost at this price. Hence, only 100 barrel oil is produced
