The total expenditures (in millions) of current dollars for pollution abatement and control during the period from 2000 through 2019 can be approximated by the function P(x) = 171.58 e^0.03x, where x = 0 corresponds to the year 2000. In what year would the total expenditures reach $222 million dollars? If this model remains accurate, when would the total expenditures reach $493 million? The expenditures would reach $222 million in the year mid-. (Simplify your answer Type a whole number.)
