I know this is a maximization problem & I know there are 8 variables but I need the coefficients.  Also need the constraints.  I believe this is a mixed integer problem but I may be wrong.  I am putting the info you give me into a cd-rom program that I will run to get an answer.  Please give me the inputs and can you some how show the work involved?  Please help me.
