I am a little thrown off by the equation I am supposed to write for the total profit in the Wood Walker problem on the solver homework, mainly because cost/unit is included in this problem and not in the Hot Tubs problem, and yet they are both asking for Total Profit. Traditionally, profit is revenue – costs, but I do not see a separate revenue column. Are we supposed to do like, # Made * Sales Price – cost/unit for this one rather than just doing SUMPRODUCT for the profit/unit and # made?
