Answer:
1. Actual Quantity = 1,850 pounds
Actual materials cost = $4,070
Standard rate per pound = $2
Standard Quantity = 6 pounds per unit * 300 units
Standard Quantity = 1,800
Standard materials cost = Standard Quantity * Standard rate per pound
Standard materials cost = 1,800 * $2
Standard materials cost = $3,600
1a. Total Materials Variance = Actual materials cost - Standard materials cost
Total Materials Variance = $4,070 - $3,600
Total Materials Variance = $470 Unfavorable
1b. Materials Price Variance = Actual materials cost - Actual Quantity * Standard rate per pound
Materials Price Variance = $4,070 - 1,850 * $2
Materials Price Variance = $370 Unfavorable
1c. Materials Quantity Variance = Standard rate per pound * (Actual Quantity - Standard Quantity)
Materials Quantity Variance = $2.00 * (1,850 - 1,800)
Materials Quantity Variance = $100 Unfavorable
2. Actual labor hours = 620
Actual labor cost = $7,130
Standard rate per hour = $12
Standard labor hours = 2 hours per unit * 300 units
Standard labor hours = 600
Standard labor cost = Standard labor hours * Standard rate per hour
Standard labor cost = 600 * $12
Standard labor cost = $7,200
2a. Total Labor Variance = Actual Labor cost - Standard Labor cost
Total Labor Variance = $7,130 - $7,200
Total Labor Variance = $70 Favorable
2b. Labor Price Variance = Actual Labor cost - Actual labor hours * Standard rate per hour
Labor Price Variance = $7,130 - 620 * $12
Labor Price Variance = $310 Favorable
2c. Labor Quantity Variance = Standard rate per hour * (Actual labor hours - Standard labor hours)
Labor Quantity Variance = $12.00 * (620 - 600)
Labor Quantity Variance = $240 Unfavorable
