You have the following information:
- cars sold in 1997 = 216
- cars sold in 2007 = 271
In order to determine the percent increase, you proceed as follow:
271 - 216 = 55 calculate the difference between the sales of both years
(55/216)(100) = 25.46% determine the associated percentage of 55 to 216
Hence, the percent increase was 25.46%
