On January 1. 2014, Thao Company purchased the following two machines for use In its production process. The recorded cost of this machine was $139, 200. Thao estimates that the useful life of the machine is 4 years with a $8, 700 salvage value remaining at the end of that time period. Calculate the amount of depreciation expense that Thao should record for Machine B each year of its useful life under the following assumptions. (Round answers to 0 decimal places, e.g. $2, 125. Round cost per unit to 2 decimal place, e.g. 1.25.) Thao uses the straight-line method of depreciation. Thao uses the declining-balance method. The rate used is twice the straight-line rate. Thao uses the units-of-activity method and estimates that the useful life of the machine is 181, 260 units. Actual usage is as follows: 2014, 59,000 units; 2015, 50, 720 units; 2016, 39, 620 units; 2017, 31, 920 units
