Your finance textbook sold 48,000 copies in its first year. The publishing company expects the sales to grow at a rate of 23 percent each year for the next three years and by 10 percent in the fourth year. Calculate the total number of copies that the publisher expects to sell in years 3 and 4. (If you solve this problem with algebra round intermediate calculations to 6 decimal places, in all cases round your final answers to the nearest whole number.)
