The doubling time of a population of flies is 8 hours.

a) By what factor does a population increase in 24 hours?
b) By what factor does the population increase in 2 weeks?

a) If the population doubles every 8 hours, then it doubles 3 times in 24 hours, since 24/8 = 3.
So 2 * 3 = 6. The increase factor is 6

b) Since a) is one full day, we now need to know how much it doubles in 14 days, which is 2 weeks. We take our factor of 6 for each day, and multiply it by 14: 14 * 6 = 84
