Question

If the population in 2001 for a Town B is 100,000, and is increasing at a rate of 1.5% every year, what
is the projected population of the Town A in 2012?
O 117,795
O 116,054
O 119,562
121,355

Answer 1

Answer:

A. 117,795

Step-by-step explanation:

We can represent this problem with the formula for exponential growth.

Where P = P0 x (1 + r)^n

P = final amount

P0 = initial amount

r = rate

n = time (years)

So, in this case, it would be:

P = 100000(1 + 0.015)^11

Solve.

P = 100000(1.177948937)
P = 117794.8937

round to nearest whole number since you can't have a percentage of a person

P = 117795
