if the population of an ant hill doubles every 10 days and there are currently 40 ants living in the ant hill, what will the ant
tatiyna
Doubling time

A=P(2)^\frac{n}{d}
A=final amount
P=initial amount
n=number of days
d=number of days to double



so
given initial is 40 ants
doubling time is 10 days
and days we want is 20 then

A=40(2)^\frac{20}{10}
A=40(2)^2
A=40(4)
A=160

the population is 160
