Reconsider the model given in Prob. 7.3-1. While doing sensitivity analysis, you learn that the estimates of the right-hand sides of the two functional constraints are accurate only to within ±50 percent. In other words, the ranges of likely values for these parameters are 5 to 15 for the first right-hand side and 6 to 18 for the second right-hand side.
(a) After solving the original spreadsheet model, determine the shadow price for the first functional constraint by increasing its right-hand side by 1 and solving again.
