the population of a town is declining at a rate of 4.1% per year. the current population is 25000. 1)what will the population be in 7 years. 2) how long will it take the population to reach 15000?

Answer 1

p = po (.959)^n

p = 25,000 (.959)^7
= 18,650

15,000 = 25, 000 (.959)^n

.6 = .959^n
ln .6 = n ln .959 or any base log

n = 12.2 years

Answer 2

just follow the steps above
