Sandhill Company purchased equipment on account on September 3, 2019, at an invoice price of $200,000. On September 4, 2019, it paid $5,300 for delivery of the equipment. A one-year, $1,995 insurance policy on the equipment was purchased on September 6, 2019. On September 20, 2019, Sandhill paid $2,700 for installation and testing of the equipment. The equipment was ready for use on October 1, 2019. Sandhill estimates that the equipment's useful life will be four years, with a residual value of $16,000. It also estimates that, in terms of activity, the equipment's useful life will be 76,800 units. Sandhill has a September 30 fiscal year end. Assume that actual usage is as follows:

# of Units		Year Ended September 30
15,600		2020
23,900		2021
20,200		2022
18,000		2023

Prepare depreciation schedules for the life of the asset under the following depreciation methods:

1.		straight-line
2.		double diminishing-balance
3.		units-of-production

(Round depreciable amount per unit to 2 decimal places, e.g. 5.27 and the final answers to 0 decimal places, e.g. 5,276.)

I have already done number 1,please follow the table i have done below to do number 2 and 3 :

1. STRAIGHT-LINE DEPRECIATION

								End of Year
Year		Depreciable Amount		Depr. Rate		=	Depr. Expense	Accum. Depr.	Carrying Amount
2020		$			%		$	$	$
2021					%
2022					%
2023					%

and also answer this question:Which method would result in the highest profit for the year ended September 30, 2021? Over the life of the asset?
