Two models of a product - Regular (X) and Deluxe (Y) - are produced by a company. A linear programming model is used to determine the production schedule. The formulation is as follows: Maximize profit = 50X + 60Y Subject to: 8X + 10Y $ 800 (labor hours) X + Ys 120 (total units demanded) 4X + 5Y $ 500 (raw materials) all variable 2 0 The optimal solution is X = 100, Y = 0. How many units of the regular model would be produced based on this solution? 120
