Chainspeaker Company produces digital thermometers. The firm began operations at the beginning of 2020 and uses a standard cost system. The standard costs for a thermometer are provided below: Direct material (0.5 kg. @ $1.00) Direct labour (1 hr. @ $10.00) Variable overhead (1 hr. @ $1.00) Fixed overhead (1 hr. @ $0.50) $0.50 $10.00 $1.00 $0.50 $12.00 The $0.50 fixed overhead rate is based on total budgeted fixed overhead costs of $17,000. There were no changes in any inventory account during the period. The company actually produced and sold 35,000 units at the following costs: Direct materials (18,000 kgs) Direct labour (36,000 hrs) Variable factory overhead Fixed factory overhead $17,280 $374,400 $34,500 $15,000 REQUIRED: 1.
