A drug company believes its new drug will sell 10,000 units in 2004. They expect two competitors to enter the market. The year in which the first competitor enters, the company expects to lose 30 percent of its market share. The year in which the second competitor enters, the company expects to lose 15 percent of its market share. The size of the market is growing at 10 percent per year. Given values for the years in which the two competitors enter, develop a worksheet that computes the annual sales for the years 2004 through 2013.
