Final answer:
The shadow prices in the primal maximization problem would be 5 for x1 and 1 for x2.
Step-by-step explanation:
In a dual minimization problem, the shadow prices of the primal maximization problem are equal to the objective function coefficients of the dual minimization problem. Therefore, the shadow prices in the primal maximization problem would be 5 for x1 and 1 for x2. So, option A) Shadow prices equal to 1(x1) and 5(x2), respectively, is the correct answer.
