PSAT Math Multiple-Choice Practice Question 70

Correct Answer: C

Explanation:

C

The question asks for a statement that is consistent with the data shown in a graph. Compare features of the graph to the answer choices and use Process of Elimination. Choice (A) is not supported by the graph because one employee had a linear decrease in energy, while the other employee's energy increased and decreased in an exponential fashion; eliminate (A). Choice (B) is also not supported; one employee had low energy after lunch, but the other employee had the highest energy level immediately after lunch. Eliminate (B). Choice (C) fits the employee who started with high energy and decreased throughout the afternoon; keep (C). Choice (D) fits neither employee: one employee's energy decreased throughout the afternoon, and the other employee's energy increased and then rapidly decreased. Eliminate (D). The correct answer is (C).
