Question

The population of a city is 125000. If the annual birth rate and death rate are 5.5% and 3.5% respectively, calculate the population of the city after 3 years.

Answer 1

Answer:

132500

Step-by-step explanation:

5.5% is 6875

3.5% is 4375

so 6875-4375=2500

so the population of the city after 3 years

132500

Answer 2

Answer:

132500

Step-by-step explanation:

Birth Rate = 5.5% x 125000 = 6875 per year

Death Rate = 3.5% x 125000 = 4375 per year

Number of Births after 3 years = 20625

Number of Deaths after 3 years = 13125

Population after Births have been counted = 125000 + 20625 = 145625

Population after Deaths have been counted = 145625 - 13125 = 132500
