Adam will spend $4,000 to rent a booth at

Adam will spend $4,000 to rent a booth at the town's annual county fair to promote his new Sandwich Shoppe. In previous years, the average food booth at the fair served 400 customers. Thus, in order to cover his costs, Adam has calculated that he must sell 400 sandwiches for $10 each.

Which of the following statements casts the most doubt on Adam's chances of breaking even at the county fair?

A. Adam should not limit himself to 400 sandwiches; he should be prepared to sell more.

B. Adam has not factored in the costs of raw materials or labor in calculating the amount of revenue he needs to generate to break even.

C. If booths in previous years averaged 400 customers, that means some booths served more than 400 and some served fewer than 400.

D. Many people prefer other types of food to sandwiches.

E. If Adam shares his booth, and the cost of the rental, with a complementary business, he will not have to sell as many sandwiches to break even.

Conclusion: To cover his costs, Adam must sell 400 sandwiches for $10 each.
Premise: Adam will spend $4000 to rent a booth

If we want to weaken this argument, we want to show that Adam's expenses will be greater than $4000, in which case the $4000 in revenue he'd receive for selling the 400 sandwiches, would not be sufficient to allow him to break even.

This is what we get from B If there are other expenses he hasn't factored in yet, the $4000 in revenue won't be enough to cover all his expenses.
