Answer:
Option b ($150,000 decrease) is the correct answer.
Explanation:
Given:
Fixed manufacturing overhead,
= $65
Units,
= 10,000
According to the question,
Current cost is:
= [tex]70\times 10,000[/tex]
= [tex]700,000[/tex] ($)
The expected cost will be:
= [tex]Fixed \ manufacturing \ overhead+(Units\times Purchase \ price)[/tex]
By substituting the values, we get
= [tex](65\times 10000)+200000[/tex]
= [tex]650000+200000[/tex]
= [tex]850000[/tex]
then,
= [tex]850000-700000[/tex]
= [tex]150000[/tex] ($)
Thus the above is the right answer.
