2. Partially automated scanner that reads the piece-goods vouchers costs about Birr1,308,900 to
make it operational. Operating costs are projected to be around Birr655,500 per year. The scanner
is expected to last for five years. The scanner's predicted net salvage value is Birr130,000,
according to estimates. The new automated system is estimated to save Birr 1,700,500 in labour
costs each year. Group 2
Calculate the net cash flows over the life of the scanner.
