Answer:
$8.5 million
Step-by-step 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 1 2 3 4
COST 40M 40M 10M 10M
YEARS 20 20 4 5
DEPRECIATION 2M 2M 2.5M 2M
Therefore Total depreciation cost for year 1 = 2+2+2.5+2 = $8.5 million
