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

`P=89,000e^(-.018t)`

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!
