Question

A population P is initially 3100 and four hours later reaches the given number. How do you find the four-hour growth or decay factor?

Answer 1

`P= P_0timese^(ktimest)`

Explanation:

If you know final population (`P`), you can calculate k (growth rate constant).

`P=3100timese^(ktimes4)`

If P is 4000 (for example)

`4000=3100timese^(4k)`

`k=0.064` 1/hour
