Answer 1

Total 2006 = 297+210+213+137+103 = 960
Total 2007 = 223+210+285+259+127 = 1104

Total percent increase = (1104−960)/960 = 144/960 = 0.15 = 15.0%
Jackets percent increase = (285−213)/213 = 72/213 ≈ 0.3380 = 33.8%

Difference = 33.8% − 15.0% = 18.8% → jackets increased 18.8 percentage points faster.
