Required:

Calculate depreciation for 2016 and 2017 using each of the following methods. Partial-year depreciation is calculated based on the number of months the asset is in service. (Do not round intermediate calculations.)

Straight-Line Depreciation
	Choose Numerator:	/	Choose Denominator:	=	Annual Depreciation
	Cost minus Salvage	/	Estimated Useful Life (years)	=	Annual Depreciation
	$176,000	/	10	=	$17,600
Year	Annual Depreciation	x	Fraction of Year	=	Depreciation Expense
2016		x		=
2017		x

Sum-of-the-years' digits depreciation
	Depreciable Base	x	Rate per Year	x	Fraction of Year	=	Depreciation Expense
10/1/2016 through 12/31/2016		x		x		=
Total depreciation expense - 2016
1/1/2017 through 9/30/2017		x		x		=
10/1/2017 through 12/31/2017		x		x		=
Total depreciation expense - 2017
