Howard visits Buffalo Wild Wings. He pays $5 and eats 5 chicken wings. His
benefit fromthe first 5 wings is $6 each. His marginal benefit for the 6 th wing is
still $6. He buys a plateof 5 more wings. After eating two more chicken wings,

wings. That is, his benefit for the remaining 3wings is $0.5 each. What should
Howard do?
A) Not eat any of the wings
B) Eat one of the wings
C) Eat two of the wings
D) Eat all three of the wings ** Answ** Answer: D
, His marginal cost of the three wings is $0. He's paying $5 for the 6th wing and
paying $0 for the 7th-10th wings. So the marginal cost of getting the 6th wing is $5
but $0 for the next four wings. This is like he's buying the 6th wing for $5 and
getting four wings for free. He will eat the wings because the marginal benefit is
greater than or equal to his marginal cost. ($0.5>$0)
Leonard also visits Buffalo Wild Wings on a Tuesday with Howard. He pays $10
and eats 10chicken wings. His benefit from the first 5 wings is $10 each and his
benefit for the last 5wings is $8 each. His marginal benefit for the 11th wing is still
$8. He buys a plate of 5 more wings. After eating two more chicken wings,
Leonard realizes he will only get $0.5 worth of enjoyment out of remaining first

he is unable to determine what his marginal benefit for the remaining chicken
wings would be. What would Raj do?
A) Purchase a set of 5 chicken wings
B) Leave the restaurant
C) Insufficient information ** Answ** Answer: C
Since the wings are sold in a set of five, Raj does not know his marginal benefit for
the other four wings.
