To satisfy a shipping contract, a total of at least 200 toys must be shipped. Each transformer toy sold results in a $2 profit, while each mental car toy produces a $5 profit. Use the graphical method of linear programming to find how many of each type should be made daily to maximize net profit? What is the maximum net profit
