Answer:
For 15 years -
After 15 years -
Step-by-step explanation:
We have that,
Initial population is 110,000 which grows by the rate 4% i.e. 0.04 for 15 years.
Since, the exponential growth is given by ,
where P is the initial population, r is the rate of interest and x is the number of years.
Thus, the required population is i.e.
.
Moreover, after 15 years i.e. x+15 years, the population will be .
Thus, the population after 15 years is .
