Answer:
Answer b: Sales of trench coats increased 8.3 percentage points faster than total coat sales.
Step-by-step explanation:
First add all the sales for 2006, and do the same for the 2007 sales, so we can compare both total sales numbers:
For 2006 we have:
103+297+210+213+137 = 960 total sales
For 2007 we have:
127+223+210+285+259 = 1104 total sales
The percent increase is calculated as the difference between the final value minus the original value, divided by the original value and multiplied by 100:
For the total number of coats we have that the percent increase is: [tex]\frac{1104-960}{960} * 100= 15[/tex]%
For the trench coats (which went from 103 sales tp 127 sales) we have the following percent increase: [tex]\frac{127-103}{103} * 100= 23.3[/tex]%
Therefore, the percent increase in trench coats was larger than the percent increase in total sales by:
23.3 % - 15% = 8.3%
