A salary increases from 40,000 to 44,000. What is the percent increase?

8 9 12 10

Correct Answer:

Explanation:

To find the percent increase, relate the change to the original amount. The salary goes from 40,000 to 44,000, so the increase is 44,000 − 40,000 = 4,000. Now compare that to the original salary: 4,000 ÷ 40,000 = 0.10. Multiply by 100 to convert to a percentage: 0.10 × 100 = 10%. So the salary increased by 10 percent. For context, 8% would be an increase of 3,200, 9% would be 3,600, and 12% would be 4,800, none of which match the actual 4,000 increase.
