The population of an area rises from 840,000 to 924,000 between two censuses. What is the percentage increase?

Answer and explanation

Correct answer: A. 10 percent

  1. Step 1: Increase divided by the starting value. Step 2. 84,000 divided by 840,000 is 0.10. Answer: 10 percent. Why not the others: 9 percent divides by the new value wrongly; 12 percent is a miscalculation; 84 percent confuses thousands.
