MODELING LINEAR PROGRAMMING
A steel manufacturer produces four sizes of 1 beams: small, medium, large and extra
large. These beams can be produced on any one of three machine type: A, B and C.
The length in feet of the I beams that can be produced on the machines per hour are

Assume that each machine can be used up to 50hours per week and that the hourly
operating costs of these machines are respectively $30, $50 and $80. Further suppose
that 10.000, 8.000, 6.000 and 6,000 feet of the different size I beams are required
weekly. Formulate the machine scheduling problem as a linear programming
