Prealgebra, Thus, 12/3

We worked out of the book -- for the first time in ages -- and the overall class level of cooperation was the worst it's been in months. Unfortunately, this means we didn't complete our work in class so there is an ASSIGNMENT -- on percents -- in the book, Ch 6, Sect 6, items 4,8,12,16, 20, 25,26,27,28,29 and 30. I hope we get back to what has become a pleasant and successful class environment tomorrow.
