I'm confused on how to figure it out utilizing the hours used.

Golden Fried Chicken bought equipment on January 2, 2018, for $21,000. The equipment was expected to remain in service for four years and to operate for 6,000 hours. At the end of the equipment's useful life, Golden estimates that its residual value will be $3,000. The equipment operated for 600 hours the first year, 1,800 hours the second year, 2,400 hours the third year, and 1,200 hours the fourth year. Read the requirements. Requirement 1. Prepare a schedule of depreciation expense, accumulated depreciation, and book value per year for the equipment under the three depreciation methods: straight-line, units-of-production, and double-declining-balance. Show your computations. Note: Three depreciation schedules must be prepared. Begin by preparing a depreciation schedule using the straight-line method.Straight-Line Depreciation Schedule Depreciation for the Year Asset Depreciable Useful Depreciation Accumulated Book Date Cost Cost Life Expense Depreciation Value 1-2-2018 12-31-2018 I = I 12-312019 I = I 12-31-2020 I = 12-31-2021 I Before calculating the units-of-production depreciation schedule, calculate the depreciation expense per unit. Select the formula, then enter the amounts and calculate the depreciation expense per unit. ( I - I )I = Depreciation per unit ( | - | )1 = Prepare a depreciation schedu e using the units-of-production method.
