Pennock Corporation produces electronic brain stimulators designed to send an electrical charge to the human brain to "jump start" brain functions. Students find it particularly helpful when taking accounting tests. The standards to produce one stimulator are attached. Also, during the year, the attached actual activity results took place for the production of stimulators. Normal activity for a year is 50,000 direct labor hours. Standard manufacturing overhead rates are computed based upon normal activity. REQUIRED: Using the attached answer sheets, calculate the following variances for the company for the year. Round all answers to the nearest whole dollar. (a) (b) Direct materials (for each material individually) price variance. Direct materials (for each material individually) quantity variance. Direct labor price (rate) variance. Direct labor quantity (efficiency) variance. (e) Variable overhead price (spending) variance. (f) Variable overhead quantity (efficiency) variance. (g) (h) Fixed overhead price (spending) variance. Fixed overhead volume variance.
