Linear Algebra/Objective Function & Constraints

Consider the problem:

“Wonder Widgets Co. manufactures three types of widgets: Standard Widget (SW), Gigantic Widget (GW), and Mini-Widget (MW) . Each widget must pass through four work centers. The SW requires 8 minutes in work center #1, 5 minutes in work center #2, 7 minutes in work center #3, and 4 minutes in work center #4. The GW requires 6 minutes in work center #1, 7 minutes in work center #2, 6 minutes in work center #3, and 4 minutes in work center #4. The MW requires 4 minutes in work center #1, 9 minutes in work center #2, 5 minutes in work center #3, and 8 minutes in work center #4. Each day, work center #1 has 7800 minutes available, work center #2 has 7500 minutes available, work center #3 has 7200 minutes available, and work center #4 has 6600 minutes available. The profits per widget are $7.50 for each SW sold, $9 for each GW, and $8.50 for each MW. If they can sell all the widgets they produce, how many of each should be manufactured each day in order to maximize profit?”
