Now, the management has to options that is rework or sell to job worker. We have to calculate net benefit for both options.
Net Benefit if company reworks and sells
= benefit- rework cost
= $ 18000 - $ 10000
= $ 8000
Net Benefit if company sell to job worker
= sale price to job worker - storage cost
= $ 13000 - $ 5000
= $ 8000
