Question

The population of a town is 80,000. If the rate of growth of population of the town is 4% per year, estimate the population of the town at the end of two years.​

Answer 1

86528

Explanation:

Solution,

Here,

The population of the town is 80000

Population growth rate=4% per year

Population after 2 years=?

Now,

Population after 1 year=80000+(4% of 80000)

Population after 1 year=83200

again,

Population after 2 years=83200+(4% of 83200)=86528

Answer 2

86,528

Explanation:

End of year 1:

80,000 + (.04)(80,000)

80,000 + 3200

83,200

End of year 2:

83200 + (.04)(83200)

83200 + 3328

86528
