Answer: Financial disadvantage of -$29,800
Step-by-step explanation:
If extra large part is produced inhouse;
= Direct materials + direct labor + Variable manufacturing overhead + Supervisor's salary + opportunity cost of making other products
= ((4.7 + 9.3 + 9.8 + 5.2) * 22,000) + 34,000
= $672,000
Cost if bought outside;
= 31.90 * 22,000
= $701,800
Financial advantage ( disadvantage) = 672,000 - 701,800
= -$29,800
