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 = [tex]\frac{Difference}{Population} * 100[/tex]
Percent decrease = [tex]\frac{19200}{160000}*100[/tex]
Percent decrease = 0.12 * 100
Percent decrease = 12%
Hence,
Percent decrease in population = 12%
