Materials Mix and Yield Variances
John’s Weed-B-Gone yard service sprays lawns to rid them of weeds. John mixes the two chemicals, Weed-X and Pest-O, in proportions depending on the climate and the particular weed problems of the season. A standard mix calls for a gallon of the mixture to combine equal parts of Weed-X and Pest-O. Weed-X has a
For the past season, John treated 648,000 square yards. He used 3,600 gallons of Weed-X and 3,000 gallons of Pest-O. He paid a total of $35,280 for the Weed-X and $72,000 for the Pest-O.

FUNDAMENTALS OF COST ACCOUNTING BUNDLE
- Direct materials efficiency, mix, and yield variances. Sandy’s Snacks produces snack mixes for the gourmet and natural foods market. Its most popular product is Tempting Trail Mix, a mixture of peanuts, dried cranberries, and chocolate pieces. For each batch, the budgeted quantities and budgeted prices are as follows:arrow_forwardNonfinancial variances. Kathy’s Kettle Potato Chips produces gourmet chips distributed to chain sub shops throughout California. To ensure that their chips are of the highest quality and have taste appeal, Kathy has a rigorous inspection process. For quality control purposes, Kathy has a standard based on the number of pounds of chips inspected per hour and the number of pounds that pass or fail the inspection. Kathy expects that for every 1,000 pounds of chips produced, 200 pounds of chips will be inspected. Inspection of 200 pounds of chips should take 1 hour. Kathy also expects that 1% of the chips inspected will fail the inspection. During the month of May, Kathy produced 113,000 pounds of chips and inspected 22,300 pounds of chips in 120 hours. Of the 22,300 pounds of chips inspected, 215 pounds of chips failed to pass the inspection.arrow_forwardJoint Direct Materials Variance Acme Manufacturing produces corrugated board containersthat the nearby wine industry uses to package wine in bulk. Acme buys kraft paper by the ton, converts it to heavy-duty paperboard on its corrugator, and then cuts and glues it into folding boxes. Theboxes are opened and filled with a plastic liner and then with the wine.Many other corrugated board converters are in the area, and competition is strong. Acme is eagerto keep its costs under control. The company has used a standard cost system for several years.Responsibility for variances has been established. For example, the purchasing agent is responsiblefor the direct materials price variance, and the general supervisor answers for the direct materialsusage variance.Recently, the industrial engineer and the company’s management accountant participated in aworkshop sponsored by the Institute of Management Accountants (IMA) at which there was somediscussion of variance analysis.
