I am about to start my second semester and we were given these to work on for practice.
Can someone explain the way they would figure these 3 questions out. I know the answers but im having a hard time figuring them out, I think I might be making them harder than they really are. I can't find problems like these in my dosage and calculations book either.
Thanks everyone, any help would really be appreciated.
