How much money would Kimberly have saved if she had bought her cheese at Deli A instead of Deli B?
(1) She bought equal amounts of Provolone and Swiss, and twice that amount of American.
(2) She bought 3.6 kilograms of cheese in all.
Kudos for a correct solution.Attachment:

800score Official Solution:Statement (1) is not sufficient by itself because we only learn the ratio of the weights of the cheeses. Kimberly might have bought just a couple hundred grams, or she might have bought many kilograms.
Statement (2) tells us exactly what we need to know: how much cheese was purchased. No matter the distribution, each kilogram of cheese would be $1 less at Deli A.
So the answer is (B).
