The salvage value is calculated by multiplying the PV of salvage value with (1.14)^No. of years
Benefits and costs are inflated with inflation rate= 3.9%

NPV and IRR value are calculated using 'NPV' and 'IRR' functions in excel
Hence,
NPV of Machine A=$14.344.13
IRR of Machine A= 26.24%
EUAW of Machine A= $2534.17
NPV of Machine B=$3347.66
IRR of Machine B= 19.96%
EUAW of Machine B= $860.88
C.
Delta IRR or incremental IRR is calculated by calculating the net cash-flows of Machine A and Machine B

D.
Here, Machine A NPW = NPV(Rate, Cash flows array from year 1 to 12) - Initial Investment
Machine B NPW = NPV(Rate,Cash flows array from year 1 to 6) - Initial Investment
