PSAT Math Multiple-Choice Question 390: Answer and Explanation

Question: 390

The graph above shows the yearly profits of an organic produce company. If the company's profits continue to grow at the same rate, in which year will it have a yearly profit that is 100% greater than its profit in 2013?

• A. 2019
• B. 2020
• C. 2021
• D. 2022

Correct Answer: A

Explanation:

A

Difficulty: Medium

Getting to the Answer: According to the bar graph, the company's yearly profits have been growing by about $10 million annually. To reach yearly profits that are 100% greater than (or double) its profits in 2013, the company would need yearly profits of 2 × $60 million = $120 -million. This is $50 million more than in 2014. At $10 million more per year, reaching this target would take 5 more years. Thus, the company should double its 2013 profits in 2014 + 5 = 2019, which is (A).
