Answer:
The machine should be replaced as it would bring about $12,500 incremental cash flow/benefits
Step-by-step explanation:
In deciding whether or not the machine should be replaced ,we can examine the issue by computing the incremental cash flows that would accrue to the company from replacing the asset rather than sticking to the old one.
The benefits from replacement:
Part exchange cash $60,000
reduction in variable manufacturing costs($13000*5) $65,000
total benefits $125,000
less cost of the new machine ($112,500)
incremental cash flow $12,500
