The Allied Group is considering two investments. The first investment involves a packaging machine, which can be used to package garments for shipping orders to customers. The second possible investment would be a molding machine that would be used to mold the mannequin parts.
The first possible investment is the packaging machine, which will cost $14,000. The second investment, the molding machine, would cost $12,000. The expected cash flows for the two projects are given below and the cost of capital to the firm is 15%. Both machines will be unusable after five years and have no salvage value.
The net cash flows for the two possible projects are given in the following table:
Year   Packaging Machine  Molding Machine 
0                          ($14000)                            ($12,000)
1                             4100                                     3200
2                             3300                                     2800
3                             2900                                     2800              
4                             2200                                     2200
5                             1200                                     2200
