(a) Suppose that the demand di for the output of the ith industry increases by one unit
Chapter 10, Problem 6(choose chapter or problem)
(a) Suppose that the demand di for the output of the ith industry increases by one unit. Explain why the ith column of the matrix (I C)1 is the increase that must be made to the production vector x to satisfy this additional demand. (b) Referring to Example 5, use the result in part (a) to determine the increase in the value of the output of the coal-mining operation needed to satisfy a demand of one additional unit in the value of the output of the powergenerating plant
