La Beano Inc. processes various beans into a healthy bean salad mix, which it sells to a food-service company. La Beano has in its budget the following standards for the direct materials inputs to produce a batch of 80 kilograms of healthy bean salad mix: 50 Kilograms of Pinto Beans at $1.05 per kilogram $52.50 30 Kilograms of Red Kidney Beans at $0.55 per kilogram 16.50 20 Kilograms of Navy Beans at $0.80 per kilogram 16.00 Totals 100 Kilograms total $85.00 Note that 100 kilograms of input quantities are required to produce 80 kilograms of bean salad mix. No inventories of direct materials are kept. Purchases are made as needed, so all price variances are related to direct materials used. The actual direct materials inputs used to produce 54,000 kilograms of healthy bean salad mix for August were: 36,400 Kilograms of Pinto Beans at $0.95 per kilogram $34,580 18,200 Kilograms of Red Kidney Beans at $0.65 per kilogram 11,830 15,400 Kilograms of Navy Beans at $0.75 per kilogram 11,550 Totals 70,000 Kilograms total $57,960 Required: 1. Compute the total direct materials rate and efficiency (usage) variances for August. 2. Compute the total direct materials mix and yield variances for August. 3. Comment on your results from Parts 1 & 2 and identify how the management may use the information about the direct materials mix and yield variances
