Identify the percent increase in total sales and the percent increase in sales of trench coats. then find which percent of
increase is greater and by how much greater it is than the other. (round your answer to the nearest tenth.)
a. sales of trench coats increased 0.7 percentage points faster than total coat sales.
b. sales of trench coats increased 8.3 percentage points faster than total coat sales.
c. total coat sales increased 2.5 percentage points faster than sales of trench coats.
d. total coat sales increased 10.7 percentage points faster than sales of trench coats.

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: %

For the trench coats (which went from 103 sales tp 127 sales) we have the following percent increase: %

Therefore, the percent increase in trench coats was larger than the percent increase in total sales by:

23.3 % - 15% = 8.3%

w'x is 0.
