Consider an economy with three sectors, Chemicals & Metals, Fuels & Power, and Machinery. Chemicals sells 30% of its output to Fuels and 50% to Machinery and retains the rest. Fuels sells 80% of its output to Chemicals and 10% to Machinery and retains the rest. Machinery sells 40% to Chemicals and 40% to Fuels and retains the rest. 1. Develop a system of equations that leads to prices at which each sector’s income matches its expenses. Then write the augmented matrix that can be row reduced to find these prices.2. Construct an exchange table for this economy
