Solve.Computer sales in the United States have increased since 1992. The polynomial can be used to approximate the number of computer sales during the years 1990-2000 where x is the number of years after 1990 and the value of the polynomial is the computer sales (in millions). Use the function to predict the number of computers sold in 2001. Round the answer to the nearest tenth of a million.
