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

The goods whose demand increases in the market when the consumer income rises are known as normal goods.
Thus, the reasoning of the student is confused as the classification of the goods on the basics of normal or inferior depends on response of the demand when there is a change in consumer's income. Thus, the student's own perception about such classification is confused.
