# Derermine the rate of growth?

Determine the rate of growth in the population of ants for each of the ten days:
Day 0 - 65 ants
Day 1 - 72 ants
Day 2 - 79 ants
Day 3 - 87 ants
Day 4 - 95 ants
Day 5 - 104 ants
Day 6 - 114 ants
Day 7 - 123 ants
Day 8 - 134 ants
Day 9 - 146 ants
Day 10 - 161 ants

I believe to solve this you need to use the equation P=PoR^(t/h) where:
P = population
Po = original population
R = rate of growth
t = time
h = time it takes for R to occur.

I've tried using the aforementioned formula, but can't determine what "h" would be? And surely the time would be the number of the day?

What have you tried? You need to show some work before anyone can help you.

I think they just want you to calculate how many new ants were produced between Day n and Day n+1 for each of the 11 days.

As a quick approximation suggestion, the population about doubles in 8 days.

The question asks for ten different values, each corresponding to the count identifying the day number.
