$\$200$ per unit for model DRB and $\$280$ per unit for model DRW. The linear programming model for this problem is as follows: Max 200DRB + 280DRW s.t. $20DRB+25DRW?32,000$ Steel available $40DRB+100DRW?120,000$ Manufacturing minutes $60DRB+40DRW?102,000$ Assembly minutes $DRB,DRW?0$ The computer solution is shown below. $\text{ Optimal Objective Value }=353600.00000$ $\begin{array}{l}\text{ ble }\\ :\text{ ase }\\ 1000\\ 1000\\ 1000\end{array}$ (a) What is the optimal solution and the total profit contribution (in \$)?
