Question
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?
Answers
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
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
just follow the steps above
