Currently the population of the metropolitan waterville area is 62,700 and is increasing at an annual rate of 3.25%. This situation can be modeled by by the equation P(t)= 62,700(1.0325)^t , where P(t) represents the total population and t represents the number of years from now. Find the population of the waterville area to the nearest hundred 7 years from now. Determine how many years, to the nearest tenth, it will take for the original population to reach 100,000. Only an algebraic solution can receive full credit Explain/show step by step on how you get the answer please and thank you
