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 __________.
- 400,000
- 500,000
- 300,000
- 200,000
Answer(s): B
Explanation:
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.
