Task 3. The following information is given about the unit standard costs: Direct materials (2 kg at $ 0.5 per kg) =$1 Direct labor (0.5 h at $ 6 per hour) = $3 Variable production overhead (0.5 h at $ 8 per hour ) =$ 4 During the last year the following transactions occurred: Raw materials purchased and used (36,700 kg) = $16,882 Direct labor (9,100 h) = $58,240 Variable production overhead = $74,600 Units produced = 18,000 Compute all 6 variances and for each of them determine if they are favored or adverse.
