Stacy, Inc., produces a product using a process that allows for substitution between two materials, Alpha and Beta. The company has the following direct materials data for its product. Standard costs for one unit of output Alpha 50 units of input at $10.00 Beta 100 units of input at $12.50 The company had the following results in June. Units of output produced 2,500 units Materials purchased and used Alpha 133,000 units at $ 9.60 Beta 242,000 units at $13.10 Required: a. Compute materials price and efficiency variances. b. Compute materials mix and yield variances. Compute materials price and efficiency variances. (Do not round intermediate calculations. Indicate the effect of each variance by selecting "F" for favorable, or "U" for unfavorable. If there is no effect, do not select either option.)
