In Example 4.3-1, compute the change in the optimal revenue in each of the following cases (use TORA output to obtain the feasibility ranges):
(a) The constraint for raw material M1 (resource 1) is 6xl + 4x2 ≤ 22.
(b) The constraint for raw material M2 (resource 2) is xl + 2x2 ≤ 4.5.
(c) The market condition represented by resource 4 is x2 ≤ 10.
