2. A furniture manufacturer makes two products - tables and chairs. Processing of these products is done on two types of machines A and B. A chair requires 2 hours on machine type A and 6 hours on machine type B. A table requires 5 hours on machine type I and no time on Machine type II. There are 16 hours/day available on machine type A and 30 hours/day on machine type B. Profits gained by the manufacturer from a chair & a table are Birr 2 and Birr 10 respectively.
A. What should be the daily production of each of the two products?
B. Use graphical method of LPP to find the solution.
Let
represent chairs and represent tables
Subject to;
As represented in the graph below, the points that satisfies the constraints is given by ;
We input both points into the objective function, we have that gives the the maximum value, hence no chair should be produced and approximately 4 tables should be produced
