Answer: Highest income=The units of Production method of depreciation with $3,412,500
Lowest income=double declining depreciation method with $18,000,000
Explanation:
a) Using Straight line depreciation method
(Cost of value - Salvage value)/ Useful life =(45,000,000 -6,000,000)/5 =$7,800,000
b)Using Units-of-production depreciation method
Depreciation Expense = (Cost – Salvage value) x (Number of units produced / Life in number of units)
=45,000,000 -6,000,000) x (350,000/4,000,000)= $3,412,500
b)Using Double-declining-balance depreciation method
Depreciation Expense = Beginning book value x Rate of depreciation
Rate of depreciation = 100% / useful life x 2= 100/5 x2 = 40 %
Depreciation expense = 40 % x $45,000,000 =$18,000,000
or you use this method directly= 45,000,000/5 x 2= $18,000,000
Now the highest income will come from the depreciation with least expense and from our calculation, the depreciation method with the least expense is from The units of Production method with $3,412,500
In the same vein, the lowest income will come from the most depreciation expense, therefore the most depreciation expense is from the double declining method with $18,000,000
