Answer:
Cole should complete the additional work and sell the cabinet for $360.
Explanation:
If Cole sells the cabinet now for $100 and taken into account that he has already spent $180, this means that:
$100-$180= -$80
He would be losing $80.
On the other side, if he completes the additional work, he would sell the cabinet $360. However, his expenses would be:
$180+$200= $380
Now, you have to subtract the costs from the selling price:
$360-$380= -$20
This means that he would lose $20.
According to that, Cole should complete the additional work because he would be lose less money.
