Answer:
The straight line depreciation will result in highest net income in year 2.
Step-by-step explanation:
a. Straight Line:
( Cost - residual value ) / useful life
( $25,000 - $3,000 ) 5
Depreciation = $4,400
b. Units of production:
( cost * annual production ) / Total expected production over life
Year 1: $25,000 * 2,000 units / 10,000 units = $5,000
Year 1: $25,000 * 3,000 units / 10,000 units = $7,500
c. Double declining balance:
100% / 5 years = 20% * 2 = 40%
Year 1: $25,000 * 40% = $10,000
Year 2: $15000 * 40% = $6,000
