XO-20 is an oil based product used to remove rust on bolts and nuts that are stuck. Its accounting system uses standard costs. The standards per 0.4-liter can of solution call for 0.71 liters of material and 4 hours of labor (0.7 liters of material are needed due to evaporation in the production process.) The standard cost per liter of material is $2.5. The standard cost per hour for labor is $13.00. Overhead is applied at the rate of $15.50 per can. Expected production is 7, 600 cans with fixed overhead per year of $35, 568 and variable overhead of $10.82 per unit (a 0.4-liter can). During 2015, B, 050 cans were produced: 13, 800 liters of material were purchased at a cost of $62, 514;10, 100 liters of material were used in production. The cost of direct labor incurred in 2015 was $384, 087, based on an average actual wage rate of $11.33 per hour. Actual overhead for 2015 was $122,000. Determine the standard cost per unit. (Round answer to 2 decimal places, e.g. 15.25.) Calculate material, labor and overhead variances. (Round answers to 0 decimal places, e.g. 125. Enter all variances as a positive number.)
