Answer 1

P= P0*(1+i/100)^t = 2700*1.04^t

Where P is the population after a certain time, P0 is the initial population, t is the time since the population is P0 and i is the growing rate. 

To know the population after 12 years we just need to plug a 12 into the t. 

P=2700*1.04^12= 4322.78. We can round it to 4323 people. 

Answer 2

2700*(1.04)*y

 

1.04 represents the growth (so, 1 + whatever your growth rate is).  Y represents the number of years, so here we would replace y with 12 and solve.

Answer 3

Rodger M. from Sunderland MA is correct!
