Let the total cost of the item be represented by C and the price be represented by P, then given that t<span>he total cost of an item including sales tax is directly proportional to its price, thus</span>
![C\propto P \\ \\ \Rightarrow C=kP](https://tex.z-dn.net/?f=C%5Cpropto%20P%20%5C%5C%20%20%5C%5C%20%5CRightarrow%20C%3DkP)
where k is a constant.
Given that <span>the total cost of a $32 item is $33.60, thus
![33.60=32k \\ \\ \Rightarrow k= \frac{33.60}{32} =1.05](https://tex.z-dn.net/?f=33.60%3D32k%20%5C%5C%20%20%5C%5C%20%5CRightarrow%20k%3D%20%5Cfrac%7B33.60%7D%7B32%7D%20%3D1.05)
Therefore, the total cost on a $55 item is given by
![C=1.05\times55=\$57.75](https://tex.z-dn.net/?f=C%3D1.05%5Ctimes55%3D%5C%2457.75)

Hello I think the answer would be 7
An angle bisector, bisects an angle into two equal small angles
14 divided by 2 is 7
Hope this helps :)
I think #4 is 4 but I'm not completely sure
You have 4 walls, 2 with length 12 feet, 2 with length 15 feet and each of them has a height of 12 feet
so you sum all the lengths and then multiply it by the height to get the total area
total length=2*(12+15)
=2*(27)
=54
total area=total length*ceiling height
=54*12
=648 feet^2 to cover all walls with wallpaper
