Math Problem Statement
An industrial system has two industries with the following input requirements. (a) To produce $1.00 worth of output, Industry A requires $0.10 of its own product and $0.50 of Industry B's product. (b) To produce $1.00 worth of output, Industry B requires $0.40 of its own product and $0.30 of Industry A's product. Find D, the input-output matrix for this system. A B D = Correct: Your answer is correct. Correct: Your answer is correct. Correct: Your answer is correct. Correct: Your answer is correct. A B
Solve for the output matrix X in the equation X = DX + E, where E is the external demand matrix E = 10,000 20,000 . (Round to the nearest whole number.)
