Answer:
The marginal cost of the 10th credit hour this semester is:
= $50
Explanation:
a) Data and Calculations:
Basic fee (Fixed cost) per semester = $100
Additional fee per credit hour = $50
Taking 10 credit hours will cost = $600 {$100 + ($50 * 10)}
b) Marginal cost is the differential change in the total cost that is incurred when the credit hours are increased by one credit hour by the student for this semester. Â It is also equal to the $50 that the college charges per credit hour.
