Jordan's family is tiling the walls of their shower. The tile costs $2.50 per square foot.
The shower is in the shape of a rectangular prism. Three walls will
be tiled.
The shower is 6 feet wide by 10 feet long, and the ceiling is 12
feet high. Both of the shorter walls are being tiled along with one
of the longer walls.
What is the total cost of the tile?

It depends on the subject for me. some exams are easier than others so i usually go through it and answer questions i know based on my general knowledge, then double check after. going through the lesson can a lot  because the exams can be  very lesson-specific, but sometimes they are ridiculously long so a lot of people don't take the time. i did find that, when i went through the lessons, i was making 100's on my exams vs strictly using + the internet and  i make 90's. 

What are the options or answer choices.
