Answer:
a) 74.5%
b) 84.3%
Step-by-step explanation:
a) If you were to refer to the glossary, as the problem statement suggests, it would tell you how to do this. Add up the scores and divide by the number of them.
Here, the 8 given scores have a total of 596%, so their mean is ...
596%/8 = 74.5%
Brandee might argue that this score <em>does not really represent her abilities</em>, because <em>her abilities were not demonstrated properly</em> on one of the tests.
__
b) Replacing the 0 score with 78% brings the total to 674%, so the new mean is ...
674%/8 = 84.3%
_____
<em>Additional comment</em>
Brandee's teacher might argue that the score <em>does</em> represent Brandee's abilities, because sometimes she fails to perform when needed.

Answer: Company B
Step-by-step explanation:
First we must calculate the area of the carpet. Variable A represents area.
So the area of the carpet is 168 square feet.
To find what company A will charge we will multiply the 168 by 2.75 they charge per square foot.
Company A charges, $462, while Company B will charge $450 for the one room.
This means Company B has the better price.
