Step-by-step explanation:
As we know that
The sunken cost is the expense already incurred and will not be recovered in the future. And as well as, it's also called past cost. That cost at the time of decision-making is useless so it would be ignored.
The incremental cost is the cost that is incurred for producing the additional units
Whereas the incremental revenue is the revenue that is earned for the sold of the additional units a. So according to the given description above, the categorization is shown below:
1. Vickery estimates that the cost associated with making the uncompleted equipment was $1,800,00 = Sunk cost
2. The cost to rebuild is $600,000 = Incremental cost
3. The sale value of the product = Incremental revenue b. As we can see that the rebuilding cost is $600,000 and the sale value is $750,000 plus the scrapped value is $100,000
So by this, he should not scrap it because it gives him an incremental profit of $150,000 ($750,000 - $600,000) if he rebuilds and sells to another buyer.
