To determine how much the firm would be willing to pay for an additional 5 units of Resource A, we need to solve the linear programming problem and then analyze the shadow price or dual value of Resource A. The shadow price tells us how much the objective function value (profit, P) would increase for a one-unit increase in the availability of a constrained resource, in this case, Resource A. Since the question asks for the value of an additional 5 units, we would multiply the shadow price by 5.Without directly solving the problem using Solver, we can't provide the exact shadow price. However, given that this is a theoretical question, we can infer that the correct answer would involve understanding the concept of shadow prices in linear programming. The shadow price reflects the maximum amount the firm would be willing to pay for an additional unit of a resource, given that all other conditions remain constant. Therefore, the answer would depend on the shadow price of Resource A, which can only be determined by solving the linear programming problem with a tool like Solver.Since we can't calculate the exact value without solving the problem, and the question seems to imply a specific value is expected, stating it's impossible to determine (A) is incorrect without further context. The correct answer (E) suggests a specific value that the firm would be willing to pay for an additional 5 units of Resource A, implying that there is a way to calculate or estimate this value based on the information given or the principles of linear programming and shadow pricing. However, without the actual calculation or Solver output, this explanation is based on the understanding of linear programming principles rather than a specific numerical solution.
