Easy, just do 45-25.50= 19.50 and then divide 19.50 by 6, and then you get 3.25. So, your answer would be $3.25.
Well if you are looking for the profit margin we need how much is was when she bought it, because it doesn't say, you can't say It's a increase or a decrease, so you could say this is a investment.
But considering you put this under mathematics I assume there is more to this question you forgot to post.
I believe the correct answer is 2.
2[(9 - 5)^5/8] = 2[4^5/8] = 2[1024/8] = 2[128] = 256
This is the concept of application of geometry and financial mathematics; To calculate for the total cost of the carpet we proceed as follows;
Total cost=[area of the carpet]*[price per square yard]
area of carpet is given by:
Area=πr^2
where;
radius,r=6 yeards
=π*6^2
=113.1 square yards
therefore the price of the carpet will be:
113.1*14
=$1,583.4
