If sector 1 produces 10 units, sector 2 produces 20 units and sector 3 produces 10 units, this combined production will use up 10 units of sector 1’s products, 13 units of sector 2’s products and 15 units of sector 3’s products. b.

If a ij = 0, then sector j requires 0 units of sector i’s products b. It is impossible to need negative units of something for production. c. If a column totals more than 1, then producing \$1 of something requires more than \$1 worth of inputs, leading to instant debt.
