Answer:
30,769.23
Explanation:
At which point the price doing the component matches the purchased amount of 12.25
100,000 / Q + 9 = 12.25
100,000 / Q = 12.25 - 9
Q = 100,000 / 3.25 = 30,769.23
At this point the cost for producing the component or bring them from abroad has the same utility (indifference zone) below this area, it is more profitable to keept outsorcing while above it, it will expense much more.
