Two processes are being considered for the production of a machine part. Process 1 requires an equipment cost of P180 000.00, a yearly operating cost of P90 000.00, and has zero salvage value at the end of its 6-year life. Process 2 has corresponding figures of P320 000.00, P72 000.00, P45 000.00 and 9-year life. If the applied MARR is 20%, compare the two processes using PW analysis

please as soon as possible . thank you

Two techniques can be used to produce expansion anchors. Technique A costs $90,000 initially and will have a $12,000 salvage value after 3 years. The operating cost with this method will be $33,000 in year 1, increasing by $2600 each year. Technique B will have a first cost of $113,000, an operating cost of $7000 in year 1, increasing by $7000 each year,and a $43,000 salvage value after its 3-year life. At an interest rate of 13% per year, which technique should be used on the basis of a present worth analysis? Notice that there are no revenues.   Please work out and do not use excel, however if you use excel please show how to input everything needed down to the formula, thank you!

PLEASE SOLVE THIS TWO PROBLEMS ASAP. THANK YOU!  A. A machine costs P388868 with a salvage value of P18029 is expected to last for 28537 hours in 5 years. In the first year of service it was used for 8077 hours. Compute the book value at the end of the first year. B.The cost of a certain asset is P486042 , its life is 5 years and scrap value is P9050 . Find the cost of depreciation after the first year using a constant percentage method.
