     Brooklyn Cabinets is a Manu facture of kitchen cabinets. The two cabinetry styles manufactured by Brooklyn are contemplator and farmhouse. Contemporary style cabinets sell for $90 and farmhouse style cabinets sell for $85. Each produced must go throng carpentry, painting, and finishing processes. The following table summarizes how much time in each process must be devoted to each style of cabinet.    
  
  Solution
Answer:
The revenue for the two types are:
For contemporary style = $90
For farmhouse style = $85
Cost of carpentry = $15 per hour
Cost of painting = $12 per hour
Cost of finishing = $18 per hour
Now,
Total cost of process in :
For contemporary style = 2 x $15 + 1.5 x $12 + 1.3 x $18 = $71.4
For farmhouse style = 2.5 x $15 + 1 x $12 + 1.2 x $18 = $71.1
Here the objective function is to maximize profit.
Let us assume we sell x contemporary and y farmhouse style:
Then the profit function is:
P = $18.6x + $13.9y this is objective function
The constraints are:
2x + 2.5y <= 3000
1.5x + y <= 1500
1.3x + 1.2y <= 1500
