Answer:
Compare the $315,000 cost to refinish the tables with the incremental revenue of $300,000 if the tables are refinished.
Step-by-step explanation:
If the tables are sold now, they would cost $305000. If an additional $315000 is spent to refinish the table, the table would the be sold for $605000, that means there would be an additional revenue of $300000 ($605000 - $305000). The company are already operating at a loss as a result of improperly finishing the table. In deciding whether to rework the tables or sell them, the company should compare the $315,000 cost to refinish the tables with the incremental revenue of $300,000 if the tables are refinished.
