This more advanced model will produce more output with greater efficiency as compare to existing machine. The cost of existing machine is $32,000 with life of 10 years, at the end of which it can be scrapped. The current market value of machine is $15,000 and there is a prospective buyer available to purchase it.

The advanced model cost $123,500 with a useful life of 8 years and a scrap value of $20,500 at the end of life.

The comparison of the two machines is as follows:

CAPACITY PER ANNUM	200,000 UNITS	230,000 UNITS
SALE PRICE PER UNIT ($)	0.95	0.95
LABOR COST PER UNIT ($)	0.12	0.08
MATERIAL COST PER UNIT ($)	0.48	0.46
