The population of a particular city is given by the function P(t) = 125,000(1.015)^t, where t is time in years and P(t) is the population after t years. What is the current population, the percentage growth rate, and the population size (rounded to the nearest whole person) after 25 years?

Hint: Percentage Growth Rate = r ⋅ 100, in A = A0(1 + r)^t

 

 A.)125,000, 1.5% semiannually, 263,155 

B.)125,000, 1.5% annually, 181,368 

C.)125,000, 15% annually, 468,750
