SAT Math Multiple Choice Practice Question 444: Answer and Explanation
6. The recipe for a pie recommends that the pie be baked for at least 50 minutes, but not more than 60 minutes. If b is the number of minutes a pie, baked within the recommended time, is baked, which of the following represents all possible values of b?
A. | b - 55 | = 5
B. | b + 55 | < 5
C. | b + 55 | > 5
D. | b - 55 | < 5
E. | b - 55 | > 5
Correct Answer: D
D Plug in a value for b, the number of minutes the pie is baked. Let's say 52 minutes, because 52 is greater than 50, less than 60, and not 55 (which is in all the answer choices). The only answer choice that works is D: |52 – 55| = |–3| = 3, which is less than 5.
