BTW if you know of any books that actually teach one how to do problems like these, please let me know. I have a hard time quantifying these problems into algebra. The book shows some easy ones and then throws this crap at you in the problems section.
I don't need help with the algebra. I just need a way to set up these problems and other word problems. It gets pretty old after a while seeing problems that the book never teaches you how to do.
the problems are show in the attachments.
the first (number 81) i really don't even know where to begin. I see what the book did and don't trust it. (how did they get to 150+x and 200-x ? I can understand multiplying x of boxes times price per box, but quantifying those two things is currently beyond me).
as for the second one (number 83), where did they come up with the number 27? the volume is 1 cubic foot. that's 36 cubic inches IIRC.
