A shipment of fruit is delivered to a warehouse. The boxes containing the fruit also contain fruit flies. Suppose we can model the population of fruit flies in the warehouse as a function of the number of days since the boxes were delivered by the equation below.
P() - 1600 - 1600(0.9)
According to this model, how many days does it take for the population to reach 320 fruit flies? Give an exact answer.
