one is the practice problems and solutions on how the work needs to be done  and the second is the actual homework. Need done by Friday afternoon. 

Show your work with all steps included. This means making clear notations on assignments (write out formulas so they are visible-digging through assignments to find formulas is not acceptable). Show your work and the steps to the answer, you may be able to give partial credit. If you leave the problem blank, it is a zero for the problem. Show your work-if you just give a answer it will be marked completely wrong.
