A used concrete pumping truck can be purchased for $125,000.

To determine the taxes due at the end of year five, we calculate the income before taxes, subtract the depreciation, and then apply the tax rate of 28%.

Year 5 Income:

Year 1 Income = $100,000

Each subsequent year increases by 5%, so Year 5 Income = $100,000 × (1.05)^4 = $121,550.63

Year 5 Operating Costs:

Year 1 Operating Costs = $65,000

Each subsequent year increases by 5%, so Year 5 Operating Costs = $65,000 × (1.05)^4 = $78,943.41

Depreciation (Straight-Line):

Depreciation = $125,000 ÷ 5 = $25,000 per year

Income Before Taxes (Year 5):

Income Before Taxes=121,550.63−78,943.41−25,000=17,607.22\text{Income Before Taxes} = 121,550.63 - 78,943.41 - 25,000 = 17,607.22Income Before Taxes=121,550.63−78,943.41−25,000=17,607.22

Taxes Due:

Taxes Due=17,607.22×0.28=4,930.02\text{Taxes Due} = 17,607.22 \times 0.28 = 4,930.02Taxes Due=17,607.22×0.28=
