Answer: -$290,000
Explanation:
The income would reduce by $290,000 if purchased from an outside supplier.
$270,000 is the cost of manufacturing 50,000 components per year.
Should they buy from outside it would cost $10 per component which would come to $500,000.
Fixed costs remain the same so we add that to the cost of purchasing outside.
$500,000 + $60,000 = $560,000
Total cost of purchasing from outside is $560,000.
The difference between the costs is =$560,000 - $270,000
= $290,000
This difference in cost would have to be accounted for from income so if purchased from outside, the income will reduce by $290,000.
