Product x: Each item sold produces $100 profit
\n" ); document.write( "Labor cost: is 3 hours for assembly, 1 hour in detail work, and 2 hours for QA & packing product.
\n" ); document.write( "Product y: Each item sold produces $150 profit
\n" ); document.write( "Labor cost: is 5 hours for assembly, 3 hour in detail work, and 2 hours for QA & packing product.
\n" ); document.write( "Company has these hours available for production for each accounting period:
\n" ); document.write( "3900 hours for assembly, 2100 hours for detail work, & 2200 hours for QA & packing.
\n" ); document.write( "----------------
\n" ); document.write( "Profit function: Profit = 100x + 150y
\n" ); document.write( "Assembly : 3x+5y<=3900
\n" ); document.write( "Detail : x +3y<=2100
\n" ); document.write( "QA&Pack : 2x+2y<=2200
\n" ); document.write( "--------------------------
\n" ); document.write( "Questions are:
\n" ); document.write( "1) How many products of both x & y should be produced to make a max & min profit?
\n" ); document.write( "----------
\n" ); document.write( "You have to develop a solution set for the Assembly/Detail/QA&Pack inequalities
\n" ); document.write( "Then you have to determine the coordinates of the vertices of this solution
\n" ); document.write( "set.
\n" ); document.write( "Then you have to substitute the x/y values of each of these vertices into
\n" ); document.write( "the Profit function to see where you get a maximum profit and where you get
\n" ); document.write( "a minimum profit.
\n" ); document.write( "-------------------------------
\n" ); document.write( "2) Now what if product y profit goes up to $170 each. How many products are needed to make a max & min profit?
\n" ); document.write( "The only thing that will change is the Profit function; it will become
\n" ); document.write( "Profit = 100x + 170y
\n" ); document.write( "To find the man or min you follow the same procedure you did with the
\n" ); document.write( "former Profit equation.
\n" ); document.write( "==============================
\n" ); document.write( "This whole procedure is called linear programming.
\n" ); document.write( "================================
