The population of Grand Island, Nebraska, grew by 600,000 people between 1995 and 2005, one-fifth more than the town council predicted.
The town council originally predicted the city’s population would grow by __________.
A. 400,000
B. 500,000
C. 300,000
D. 200,000
Correct Answer: B
Explanation/Reference:
Let x = the original estimate. An additional one-fifth would be 6,5x, or 120% of x. The equation can be expressed as 1.2x = 600000. To solve for x, divide both sides of the equation by 1.2. x = 500,000.
