Answer:
$405,000
Explanation:
The calculation of total amount is shown below:-
If the company disposes of the equipment to buy the new equipment, the sunk cost will be the old equipment's book value.
Sunk cost = Book value of the old Equipment
Sunk cost = Cost of equipment - Accumulated Depreciation
= $550,000 - $145,000
= $405,000
Therefore for computing the sunk cost we simply deduct the accumulated Depreciation from cost of equipment
