Write a system of linear equations to determine how much you will have to sell in order to make a profit. <> Here they state the question (again!) This is such an awesome project. With all that in mind, I would have all the students in my average classes do a rough draft (of both the letter and the attachment). And this professional business letter format is so foreign to them. So I would usually collect the rough drafts, make general comments on them and hand them back. Students love this game and they really get into completing their work while playing it. One error could lose a client for them. So, k=j−12. Every project needs to have a focus and goal. I've been working with advanced students for the last few years and the peer editing can be productive with them. ; One example is a business organization. They can lay on the schmooze pretty thick because they are wooing a client.
