c. Working Hours $___31,482___:

d. Sum-of-the-years-digits $48,600:

e. Declining balance (use 20% as the annual rate) = $54,704

Explanation:

Cost of machinery purchased on May 1, 2020 = $315,600

Estimated useful life = 10 years

Salvage value = $18,600

Depreciable amount = $297,000

Production units = 237,600

Working hours = 25,000

Straight-line method:

Annual Depreciation Expense = $29,700 ($297,000/10)

Production units:

Depreciation per unit = $1.25 ($297,000/237,600)

Working hours:

Depreciation per hour = $11.88 ($297,000/25,000)

Sum-of-the-years-digits = 55 years;

Depreciation per year = $5,400 ($297,000/55)

Declining balance rate = 20% (100/10 * 2)

During 2021:

Straight-line:

Depreciation expense = $29,700

Machine hours used = 2,650

Depreciation expense = 2,650 * $11.88

= $31,482

Production units = 30,300

Depreciation expense = 30,300 * $1.25

= $37,875

Sum-of-the-years-digits:

Depreciation expense = 9 * $5,400 = $48,600

Declining balance:

2020 = $315,600 * 20%  * 8/12 = $63,120 * 8/12 = $42,080

2021 balance = $273,520

2021 Depreciation expense = $273,520 * 20% = $54,704

a. $48.75
