Solution:

The Given model to Predict the population

P=P_{0}(1.005)^{\frac{t}{3}

                               ----------------------------------(1)

The population increases by 0.5 % every n months.

Initial Population = 215

Final Population

=215+215\times \frac{0.5}{100}\\\\=215+1.075\\\\=216.075

Substituting the value of , Initial and final Population in equation 1,

216.075=215\times (1.005)^{\frac{t}{3}}\\\\  (1.005)^{\frac{t}{3}}=\frac{216.075}{215}\\\\  (1.005)^{\frac{t}{3}}=(1.005)^{1}\\\\ \frac{t}{3}=1\\\\ t=3

t=3 years =36 months

The value of n is equal to 36 months.

1. He used his fingers; he put 1 finger, then another finger, and got 2 fingers up. The answer is 2.

2. He remembered it; usually Kindergarteners learn this and this is very easy to remember.

3. He used the things around him; I have 1 crayon then add another, how many do I have? 2.
