Answer:
The marginal cost of an additional unit of output is $145
Explanation:
The computation of marginal cost of an additional unit of output is shown below:
= Change in total cost ÷ change in production level
where,
Change in total cost = Increased cost - previous cost
= $9.4 million - $6.5 million
= $2.9 million
Thus, change in total cost is $2.9 million
And, change in production level = New production level - existing production level
= 70,000 - 50,000
=20,000
Thus, change in production level is 20,000
Now,
Apply the above values in the formula which is equals to
= $2.9 million ÷ 20,000
= $145
Hence, the marginal cost of an additional unit of output is $145
