If we assume the total sales to be 100 in the first year, IBM's sales would go up by 50% (from 28 to
42) contributing an increase of 14 to the total sales value.
Similarly, Apple's increase of 15% would contribute an increase of 2.1 to the total sales value. The
net change would be 14 + 2.1 on 100. (i.e., 16.1%)
3. In 2005, the average unit sale price of an IBM PC was approximately (in US$)
IBM accounts for 28% of the share by value and 10% of the share by volume.
28% of 1650000 = 28 x 1650000/100 = 462000
10% of 1500 = 10 x 1500/100 = 150
Therefore, average unit sale price = 462000/150 = 3080.
