(a) James Company bought equipment for $460,000 on 22 February 20Y1. The machine had an estimated residual value of $60,000, and had estimated useful life of 10 years, or had an estimated operation output of 100,000 hours. The year-end date of the company is 31 December. Calculate the depreciation on the equipment in these two years using the following methods. 20Y1 2012 (i) Straight-line (using half-year convention) $ $ (ii) 200%-declining-balance (using full-year depreciation in the first year) $ (iii) Units-of-output method (hours of operation: 10,000 in 20Y1; 12,000 in 20Y2) (b) Solar Company purchased equipment for $27,000 on 1 July 20X1.

Until the end of the second year at 31 December 20X2, the Company sold the equipment for $12,500.
