Answer:
1. a. The materials price and quantity variances
Material price variance: Standard cost per micron is $1.50 and actual cost per micron is $1.48. So, price variance is 1.48 - 1.5 = $(0.02) per micron
Quantity variance: Based on standard bill of material, Dawson Toys need 3,000 x 6 = 18,000 microns to produce 3,000 Maze toys. Actual consumption volume is 25,000 - 5,000 = 20,000 microns. So, quantity variance is 20,000 - 18,000 = 2,000 microns.
1. b. The labor rate and efficiency variances
Actual labor rate = Actual labor cost / Actual hour = 88,000/4,000 = $22 per hour.
Efficiency variance = Actual labor rate - Standard labor rate = 22 - 21 = $1 per hour.
2. Prepare a brief explanation of the possible causes of each variance.
Direct material cost variance: Total actual material cost is 20,000 x 1.48 = $29,600, higher than standard material cost of 18,000 x 1.5 = $27,000. This is mainly due to higher production waste as compared to standards.
Direct labor cost variance: Total actual labor cost is $88,000, higher than standard labor cost of 4,000 x 21 = $84,000. This is mainly due to lower labor rate per hour than expected.
