Answer :
Answer:
E) $199
Explanation:
As a rational individual, you should only sell your iPad if the marginal benefit is larger than the marginal cost. In this case the marginal benefit is $200, so the marginal cost must be lower than $200, and only option E ($199) is lower. If the shipping costs were higher than $200, you would be losing money.
*Receiving $1 for an iPad might be rational but not very intelligent.
