Suppose an insecticide is applied to a crop to eradicate fruit flies. Assume that 1/1,000,000 fruit flies possess an enzyme that breaks down the insecticide into non-toxic metabolic products. Assume further that as the normal fruit flies die off quickly, a population of the resistant flies increases geometrically (that is, 1, 2, 4, 8 ...) If a new generation occurs every 62 days, in how many days will the fruit fly population be restored?
