One year, the population of a city was 160,000. Several years later it was 140,800. Find the percent decrease.
LekaFEV [45]

Answer:

Percent decrease in population = 12%

Step-by-step explanation:

Given that:

Population of city = 160,000

Population of city after several years = 140,800

Difference= 160000 - 140800 = 19200

Percent decrease = \frac{Difference}{Population} * 100

Percent decrease = \frac{19200}{160000}*100

Percent decrease = 0.12 * 100

Percent decrease = 12%

Hence,

Percent decrease in population = 12%
