A furniture manufacturing company plans to make two products. chairs and tables from its available resources, which consists of 400 board feet of mahogany timbers and 450 man-hours of labour. it knows that to make a chair requires 5 board feet and 10 man-hours and yields a profit of 450, while each table uses 20 board feet and 15 man-hours and has a profit of 80.how many chairs and tables should the company make to get the maximum profit under the above resource constraints? Formulate the above as an LPP.
+130477 We are trying to maximize
P = 450x + 80y
Subject to these constraint equations:
x ≥ 0, y ≥ 0, 5x + 20y ≤ 400 and 10x + 15y ≤ 450 ..... where x is the number of chairs produced and y is the number of tables produced
Here's a graph of the feasible region......https://www.desmos.com/calculator/mbousof3x9
The maximum profit occurs at the "corner point".... (24, 14)
So....produce 24 chairs and 14 tables to maximize the profit....

CPhill's solution is 24 chairs and 14 tables
This gives a profit of
24×450+14×80=11920 dollars
I will also check that this fits the limitations.
mahogony = 24*5+14*20=400 good
hours = 24*10+14*15=450 good

My solution is 45 chairs and no tables
This gives a profit of
45×450=20250 dollars
I will also check that this fits the limitations.
mahogony = 45*5=225 good
hours = 45*10=450 good
Here if my graph. The movable line represents profit. Basically I just added this to CPhill's graph.
