thank you in advance:))

Stan Holbert, the purchasing manager for Champion Industries, recently attended a meeting with a potential supplier, Wallace Materials. At the meeting, a Wallace manager demonstrated a material that was easier to handle and shape than the material currently used by champion Industries. Assume that annual production is 150,000 units. Calculate the cost savings associated with using the new material. b. Stan knows that because of an overworked accounting department, standard costs will not be updated in a timely manner. Suppose that the company switches to the new material. What are the expected material and labor variances if standards are not updated? c. Suppose purchase price variances play a prominent role in the evaluation of Stan's job performance. Will he be inclined to suggest use of the new material
