This is a “student-produced response” question. In these, you have to generate an answer rather than make a choice.
Each canvas bag will hold exactly 5 pounds of Famous Joe’s tomatoes. How many bags will be necessary to hold 5 kilograms worth of these same tomatoes? (1 kilogram = 2.25 pounds
The math on this one is easy enough. A five kilogram bag would weigh 5 x 2.25, or 11.25 pounds. If one bag holds five pounds, then how many bags will we need to hold 11.25 pounds? The temptation here is to divide 11.25 by 5, which would give you 2.25. However, you need to look carefully at the wording of this question: “How many bags will be necessary to hold 5 kilograms. . .?” The tomatoes would take up 2.25 bags’ worth of space, but to do that you would need three bags. This is the nasty kind of trick that the SAT writers will send your way every once in a while. The good news is that they don’t do that too much—just enough to keep you on your toes. The answer is 3.
