Question

The population of Preston is 89,000 and is decreasing by 1.8% each year. Write a formula that models the population as a function of time t.

Answer 1

Answer:

$P=89,000e^{-.018t}$

Step-by-step explanation:

I used this equation formula and just input the numbers given:

$P=P_{o}e^{rt}$

Where

P= final population

$P_{o}$ = original population

r = rate of growth

t = time

Hope this helps!
