Question

Stacy is going to the state chili cook-off with her friends but can only stay for 4 hours. The event offers two different pricing structures. Stacy can purchase an all day pass with unlimited food samples for $15.00 or she can pay an admission fee of $3.00 and pay $2.00 for each bowl of chili. If she is planning on having 5 bowls of chili, which deal should she take?

 A. 

both pricing structures ending up costing the same amount

 B. 

the all day pass with unlimited food samples for $15.00

 C. 

Stacy does not have enough money to go to the fair

 D. 

the admission fee of $3.00 plus $2.00 for each bowl of chili

Answer 1

2(5) + 3 = $13 for 5 bowls of chili

A. 13 ≠ 15, so no

B. 15 > 13, so unless she's not worried about spending $2 more, this is probably out.

C. Well, if she didn't have the money, she wouldn't be going. Duh!

D. 13 < 15. Ding ding ding! Here's our answer.

Answer 2

The problem as stated suggests that Stacy has the money for the fair, but does not definitively rule answer C out (perhaps she is planning on borrowing money from her friends). However, this is a mathematical question, not a legal one, so the mathematics should be examined. If Stacy chooses the first option, she pays $15 and does not have to pay anything for her bowls of chili. If Stacy chooses the second option, she pays $3 immediately to enter. If she then eats 5 bowls of chili at $2 per bowl, she will pay 5*$2 = $10 for the bowls of chili, plus the $3 entry fee, which adds to $13. Since this is less than the $15 for the unlimited plan, the answer to the problem is (D).
