Answer: It would serve them better to sell off the units as scrap. Please refer to Explanation
Step-by-step explanation:
We'll answer this in 2steps. First we will see how much we wll make if we seel as scarp and then compare that to the cost of reworking.
Selling as Scrap
= Selling price * No. of units
= 3.5 * 10,000
= $35,000
Reworking
= Selling price * No of Units - ( opportunity cost * no. of units) - cost to rework units
Opportunity Cost
If the units are sold as is, the company will be able to build 10,000 replacement units at a cost of $5.50 each, and sell them at the full price of $9.00 each.
= Selling price - cost * units
= 9 - 5.5 * 10,000
= $35,000
So going back to our formula,
= (Selling price * No of Units) - opportunity cost - (cost to rework units * no of units)
= (9 * 10,000) - 35,000 - (4.8 * 10,000)
= $7,000
It would serve them better to sell off the units as scrap.
