Avogadro Solutions prepares specialized liquid solutions that are used in a variety of industries. Its accounting system uses standard costs. a. The standards per half-liter flask of solution call for 2.0 liters of material and 4.0 hours of labor. (2.0 liters of material are needed due to evaporation in the production process.) b. The standard cost per liter of material is $3.00. c. The standard cost per hour for labor is $15.00. d. Overhead is applied at the rate of $14.50 per flask. Expected production is 6,000 flasks with fixed overhead budgeted at $30,000 for the year. You do not need to separate fixed and variable overhead for this problem. We are only calculating the one-way overhead variance. e Variable overhead is applied at a rate of $9.50 per unit (a half liter flask). During 2019: 5,000 flasks were produced; 12,000 liters of material were purchased at a cost of $42,000; 10.100 liters of materials were used in production. Direct labor incurred was $302,375 (average wage rate of $14.75 per hour) Actual overhead was $70,000. Required: a. Determine the standard cost per unit when you expect to produce 6,000 units. Round your answer to the nearest cent. b. Calculate all material variances. c. Calculate all labor variances. d. Calculate the one-way overhead variance. e. List a possible cause for all the above variances
