Eastern Textiles can use any of three different processes for weaving a commemorative Newfoundland tartan. Each process has a variable cost per square metre for weaving the fabric. Due to recent advances in weaving machine technology, there is also a fixed setup cost for the weaving machine used by each process. The table shows the setup cost, variable production cost, and production for each of the three processes.
Process | Setup Cost | Production cost ($ per m^2) | Capacity (m^2) |
1 | $500 | $0.17 | 30,000 |
2 | $800 | $0.14 | 35,000 |
3 | $1200 | $0.12 | 45,000 |
The company wants to minimize the total cost of production, subject to the constraint that it has to produce 50,000 square metres of fabric daily to meet demand.
