Final answer:
To find the individual cost of each machine, set up an equation using the total cost of the machines as $217,000. Without knowing the individual costs, we cannot determine the result of selling Machine No. 3.
Step-by-step explanation:
To find the individual cost of each machine, we can use the given information about the total cost. Eastwood Manufacturing bought three used machines in a lump-sum purchase of $217,000.
Let's assume Machine 1, Machine 2, and Machine 3 have costs x, y, and z respectively.
Since the total cost of the machines is $217,000, we can set up an equation: x + y + z = 217,000.
We don't have enough information to solve this equation, as we don't know the individual costs of the machines. Therefore, we cannot determine the result of selling Machine No. 3 for its appraised value.
