Answer:
18 dollars
Step-by-step explanation:
Marginal cost can be defined as the additional cost to produce every additional unit of a certain good. In mathematical terms;
Marginal cost = change in cost / change in quantity
For seven jackets, we have to find the difference between the cost of seven jackets and the cost of six jackets as follows
$101 - $83 = $18
Since the change in quantity is one, our marginal cost comes to $18.
