1. Consider the following sensitivity report from Excel Solver (for questions 1 and 2): Variable cells Constraints If the coefficient for Activity 1 in the objective function changes to \\( \\$ 50 \\), then the objective function value: a. will decrease by \\( \\$ 450 \\). b. is \\( \\$ 0 \\). c. will decrease by \\( \\$ 2750 \\). d. will remain the same. e. can only be discovered by resolving the problem. 2. Considering the sensitivity report from question 1 (above): If the coefficient of Activity 2 in the objective function changes to \\( \\$ 100 \\), then: a. the original solution remains optimal. b. the problem must be resolved to find the optimal solution. c. the shadow price is valid. d. the shadow price is not valid. e. None of the choices is correct
