plz solve this question

Consider the following linear program Max 3A + 8B 3A + 68 15 BA+ 68 20 a) Use Excel solver the find the optimal solution and generate the sensitivity report What is the optimal solution? Use the sensitivity report to answer the following questions: b) assume that the objective function coefficient for a changes from 3 to 5. Does the optimal solution change? c) Assume that the objective function coefficient for Aremains 3, but the objective function coefficient for 8 changes from 8 to 14. Does the optimal solution change? d) Based on the shadow price and the right-hand-side range information in Sensitivity report, what conclusion can you draw about the effect of changes to the right-hand side of the constraint 1
