Answer:
$8.5 million
Explanation:
On January 1, year 1, a company purchased equipment for $100 million.
The equipment consists of four major components, of which two components comprise 80% of the total cost and each has a 20-year useful life.
The remaining two components have costs of $10 million each; one of them has a useful life of four years, and the other has a useful life of five years.
Straight-line method of depreciation is given by the formula: Cost / Number of years
COMPONENT Â Â Â Â 1 Â Â Â 2 Â Â Â 3 Â Â Â 4
COST Â Â Â Â Â Â Â Â Â 40M Â 40M 10M 10M
YEARS Â Â Â Â Â Â Â Â Â 20 Â Â 20 Â Â 4 Â Â Â 5
DEPRECIATION Â 2M Â Â 2M Â 2.5M Â 2M
Therefore Total depreciation cost for year 1 = 2+2+2.5+2 = $8.5 million
