Answer: Sales of jackets increased 18.8 percentage points faster than total coat sales.
Step-by-step explanation:
From the given pie-charts, Sales of jackets in 2006=213
Sales of jackets in 2007= 285
[tex]\text{Increase in Sales of jacket = Sales in 2007-Sales in 2006}\\\\\Rightarrow\text{Increase in Sales of jacket = }285-213=72[/tex]
The percentage increase in sale of jacket =[tex]\dfrac{\text{Increase in sales}}{\text{Sales in 2006}}\times100[/tex]
[tex]=\frac{72}{213}\times100=33.8028169014\%\approx33.8\%[/tex]
Total sales in 2006=[tex]103+297+210+213+137=960[/tex]
Total sales in 2007=[tex]127+223+210+285+259=1104[/tex]
[tex]\text{Increase in Total coat's sales = Total sales in 2007-Total sales in 2006}\\\\\Rightarrow\text{Increase in Total sales = }1104-960=144[/tex]
bbb
The percentage increase in total coat's sales =[tex]\dfrac{\text{Increase in Total sales}}{\text{Total sales in 2006}}\times100[/tex]
[tex]=\frac{144}{960}\times100=15\%[/tex]
Clearly, 33.8 >15
Hence, the percentage increase in sales of jackets is greater than percentage increase in the total coat's sales.
Difference in percent of total coats sales and jackets sales =[tex]33.80\% -15\% =18.80\%[/tex]
Hence, Sales of jackets increased 18.8 percentage points faster than total coat sales.
