Given the input output matrix and the external demand are as the matrices below.

A= 0.4 0.6 0
0.4 0.3 0.2
0.1 0 0.4

D= 72
150
58

By using the Leontief Input-Output model, determine the production levels necessary to satisfy the final demand.

I just dont know how to start this question. Any quick hint or formula how i can get the answer?

no idea - my first step would be to review the Leontief Input-Output model ...
