Given that Marymount Township secured the construction of a power plant, which opened in 1990. Once the power plant opened in 1990, the population of Marymount increased by about 20% each year for the first ten years and then increased by 5% each year after that
Let P0 be the population in 1990
Then we have in 2000 the population is
with this initial population for next growth we have in 2010 the population would be
, where P = population is 2000
a) Given that
b) we use the exponential equation and solve for initial population in 2000.
c) we have
