I would really appreciate help with this Linear Algebra problem. Thanks!

Suppose an economy has four sectors: Mining, Lumber, Energy, and Transportation. Mining sells 10 % of its output to Lumber, 70% to Energy, and retains the rest. Lumber sells 10 % of its output to Mining, 50 % to Energy, 20% to Transportation, and retains the rest. Energy sells 30% of its output to Mining, 15% to Lumber , 30 % to Transportation, and retains the rest. Transportation sells 15 % of its output to Mining, 10% to Lumber, 40% to Energy, and retains the rest. a. Construct the exchange table for this economy. b. Find a set of equilibrium prices for this economy a. Complete the exchange table below. Distribution of Output from: Lumber Energy 3 ransnortation Mining Purchased by: 15 Mining 15 1 Lumber 5 25 4 Energy Transportation 0 3 35 (Type integers or decimals.) b. Denote the prices (that is, dollar values) of the total annual outputs of the Mining, Lumber, Energy, and Transportation sectors by p PL. PE, and pT, respectively. If PT $100, then PM=$[ PL = $ [ , and PE $ (Round to the nearest dollar as needed.) ?
