Answer:
Average investment = $53,000
Explanation:
As per the information provided,
The cost of machine = $56,000
Life of the machine = 9 years
Salvage value = $0
Therefore, depreciation each year as per straight line method =
Therefore value of machine in the beginning = $56,000
Value at year end = $56,000 - $6,000 = $50,000
Thus average investment for the year =
And it will decrease by constant $6,000 each year
Year 2 Average investment = $53,000 - $6,000 = $47,000
As Accounting return is calculated every year separately the average investment will be calculated every year, that is for year 1 it is =
Average investment = $53,000
