Answer:
Average price for crab leg= $1.428
Marginal cost for extra crab leg= $0
Step-by-step explanation:
Gustavo pays $39.99 for crab legs
Eats 28 crab legs on Fridays
To get the average price of crab legs divide the total price by the number of crab legs.
Average price= Total price/Number of legs
Average price = 39.99/28
Average price= $1.428
The marginal cost of an extra crab legs is the cost of producing an extra crab leg for Gustavo.
Since Gustavo only eats 28 crab legs and no more
Marginal cost for extra crab leg= $0
