work out the percentage increase in the number of computers sold.
give your answer to an appropriate degree of accuracy

Number of computers Bytes sold in 2003 = 620
Number of computers Bytes sold in 2004 = 708
Then
Number of computers more sold by Bytes in 2004 compared to 2003 = (708 - 620)
                                                                                                                = 88
Percentage increase in the number of computers sold = (88/620) * 100 percent
                                                                                        = 8800/620 percent
                                                                                         = 880/62 percent
                                                                                       = 14.19 percent
So the percentage increase in sales of Bytes from 2003 to 2004 is 14.19%. I hope this is the answer you were looking for.

If you would like to know what is the percentage increase in the number of computers sold, you can calculate this using the following steps:

x% of 620 computers (in 2003) is 708 computers (in 2004)
x% * 620 = 708
x/100 * 620 = 708     /*100/620
x = 708 * 100 / 620
x = 114.19%

114.19% - 100% = 14.19%

The correct result would be 14.19%.
