having trouble with both MACRS depreciation and straight-line depreciation. Equations help a lot! Thanks in advance

A company has acquired a vehicle and light trucks costing $100,000 in the first quarter of the tax year and research equipment costing $500,000 in the fourth quarter of the tax year, so the mid-quarter convention is appropriate for depreciation calculations (more than 40% of depreciable cost is in the last quarter). The assets qualify as 5-year life depreciable property. Compute the MACRS depreciation and straight-line depreciation for each year
