Question

The population of Centerville is 16,400; 75% of the people live in urban areas and 25% of the people live in rural areas. The population of Centerville is expected to increase 5% in the next 10 years. If the percent of people living in urban areas remains the same , how many people will be living in urban areas in the next 10 years

Answer 1

The number of people living in urban areas is 16,400 x .75 = 12,300

 

12,300 * .05 = 615 new people in urban areas.

12,300 + 615 = 12,915

 

or: 16,300*1.05 = 12.915

 

Alternatively:

 

16,400 * 1.05 = 17,200

 

17,220 * .75 = 12,915
