Using this model to determine the percentage of spam in the year 2006 to the nearest tenth of a percent?

Question

Suppose that the function P=11+14In x represents the percentage of inbound e-mail in the u.s. that is considered spam where x is the number of years after 2000

x = 2006 - 2000 = 6

Now plug into your calculator:
