A population of 1570000 decreases 2.3% each year. what is the population after 17 years
The population can be modeled by the equation
Pn = P(1 + a)^n, where
P is the starting population, and P = 1570000
Pn is the population after n years
a is the annual rate of increase of population, and a = -0.023 (a is negative becaise popln is decreasing)
After 17 years,
P17 = 1570000*(1 - 0.023)^17
P17 = 1570000*(0.977)^17
P17 = 1570000*0.673298
P17 = 1,057,078
