106. Required:

Compute depreciation expense for 2006 and 2007 and the book value of the spooler at December 31, 2006 and 2007, assuming the sum-of-the-years'-digits method is used.

Answer:

Denominator = n(n+1)/2 = (8 x 9)/2 = 36

Depreciable base = $40,000 - 4,000 = $36,000

2006 depreciation expense: 8/36 x $36,000 = $8,000

2007 depreciation expense: 7/36 x 36,000 = $7,000
