Final answer:
The depreciation expense for each of the remaining 31 years is $2,161.29.
Step-by-step explanation:
To determine the depreciation expense for each of the remaining 31 years, we need to divide the residual value by the remaining years. In this case, the residual value is $67,200 and the remaining years is 31. So the depreciation expense for each year would be:
Depreciation Expense = Residual Value / Remaining Years
Depreciation Expense = $67,200 / 31
Depreciation Expense = $2,161.29
Therefore, the correct answer is option c) $2,161.29.
