Question:
Let an economy contain clothing, housing and food industries. Let $1 in clothing require $0.30 in clothing, $0.30 in housing and $0.10 in food, while $1 in housing takes $0.10 in clothing and $0.50 in housing, and $1 in food uses $0.50 in clothing, $0.10 in housing, and $0.70 in food. Let the demand be $700 in clothing, $1400 in housing, and $2100 in food for the first quarter, and $1400 in clothing, $700 in housing, and $1400 in food in the second quarter.
Issue:
I am having a difficult time getting the inverse of (I-C). I have done the matrix inverse steps multiple times and I keep getting a different answer than what I get when I check the math. I'd love to see the step by step process of finding (I-C) -1 to see where I am going wrong. Completion of the problem would be helpful in checking my steps. I've attached a couple of my tries as photos.
