Hi, I'm having trouble with this homework problem. Any help would be appreciated. The numbers are in the attachment

7.

Find the consumption matrixAand demand vectorD0 for this table.

8.

Find the production vectorXfor the consumption matrixAand demand vectorD0.

9.

If the demand for construction increases by 1 million, how much will the production of the transportation, communication, and utilities sector have to increase to compensate?

10.

Which three sectors are most affected by an increase of $1 million of demand for construction?

11.

If the entirejth column of the matrix (I-A)-1 is added, the result is the amount of new production in theentire economycaused by an increase of $1 million in demand for thejth sector. How much new production is produced in the entire economy by an increase of $1 million in demand for construction?

12.

What would it mean for the (i,j) entry in (I-A)-1 to be zero?
