Answer:

Population of Leavetown in 100 years from now will be 11,324

Explanation:

To find the decrease in population after a certain years, we will work with the formula below:

P(t) = Po (1 - r)^t

Where

P(t) = new population over time

Po = initial population

r = rate of decrease

t = time taken

In this case

Initial population Po = 123,000

Rate of decrease r = 2.357%

Time t = 100

Therefore

P(t) = Po (1 - r)^t

P(100) = 123,000 ( 1 - 2.357/100)^100

P(100) = 123,000 ( 1 - 0.02357)^100

P(100) = 123,000 (0.97643)^100

P(100) = 123,000 ( 0.092068)

P(100) = 11,324.4349

P(100) = 11,324

Population of Leavetown in 100 years from now will be 11,324
