your finance text book sold 47,500 copies in the 1st year the publishing company expects the sales to grow at a rate of 23.0 percent for the next three years and by 12.0 percent in the fourth year calculate the total number of copies that the publisher expect to sell in year 3 and 4

My interpretation of the wording

first year = 47500
2nd year = 47500(1.23)
third year = 47500(1.23)^2
fourth year = 47500(1.23)^2 (1.12)
= .....
