Answer:
the list of assets is missing, so I looked for a similar question and found the following:
MACRS depreciation for machinery is 10 years, and the depreciation % for the first year using the half year convention is 10% ⇒ depreciation expense = $70,000 x 10% = $7,000
MACRS depreciation for computer equipment is 5 years, and the depreciation % for the first year using the half year convention is 20% ⇒ depreciation expense = $10,000 x 20% = $2,000
MACRS depreciation for the delivery truck is 5 years, and the depreciation % for the first year using the half year convention is 20% ⇒ depreciation expense = $23,000 x 20% = $4,600
MACRS depreciation for furniture is 7 years, and you can use the mid-quarter convention since furniture represents more than 40% of total assets placed in to service. The depreciation % for the first year, second quarter using the mid-quarter convention is 17.85% (the half year convention depreciation rate is 14.29%) ⇒ depreciation expense = $150,000 x 17.85% = $26,775
total depreciation expense = $40,375
