The task of this question is to identify a 25% or greater percent decrease between the two prices for the different car models. Use the percent change formula for all of the models to solve this question. Start with model A. Using the calculator, subtract 9,500 from 12,000
to get 2,500. This is the difference. Divide it by the original, 12,000, to get about 0.2, which when multiplied by 100 is 20%. Since 20% is less than 25%, eliminate (A). Try the next one. 16,000 − 13,000 = 3,000. Divide 3,000 by 16,000. The result is less than 25%, so eliminate (B).
Repeat this process for each of the answer choices. Choices (C), (D), and (F) are the correct answers.
