BOB 2

This unit I've had some trouble with. I understand a majority of what needs to be done but these problem solving questions are pulling me down. I'm sure a lot of people feel the same about them. It's not that hard, i just happen to get confused along the way most of the time. But working on it in class is helping me understand how i do these things. I don't have much else to say, but good luck everyone on the pre test and test! ..
