Solution
1) a) Materials Price Variance = (Std Price - Actual Price)*Actual Qty purchased
Actual price = Actual cost of materials purchased/Actual Qty purchased
= $266,625/13,500 ounces = $19.75 per ounce
Materials Price Variance = ($21.00-$19.75)*13,500 ounces = $16,875 F
Materials Quantity Variance = (Std Qty - Actual Qty used)*Std Price
Actual Qty used = Actual Qty of materials purchased - Ending Inventory
= 13,500 ounces - 4,200 ounces = 9,300 ounces
Std Qty = Actual units produced*Std Qty per unit
= 3,800 units*$2.40 ounces = 9,120 ounces
Materials Quantity Variance = (9,120 - 9,300)*$21.00 per ounce = ($3,780) U
1) b) The company should sign the contract with the supplier because the materials price variance is favorable for $16,875.
2) a) Labor Rate Variance = (Std Rate - Actual Rate)*Actual Hrs worked
Actual Hrs worked = 24 technicians*140 hrs = 3,360 hrs
Std Hrs = Actual units of output*Std hour per unit
= 3,800 units*0.80 hrs = 3,040 hrs
Labor Rate Variance = ($15.00 - $14.50)*3,360 hrs = $1,680 F
Labor Efficiency Variance = (Std Hrs - Actual Hrs)*Std Rate
= (3,040 - 3,360)*$15.00 = ($4,800) U
2) b) No, new labor mix should not be continued because new labor mix increases overall labor costs as there is an unfavorable labor efficiency variance of $4,800.
3) Actual Variable OH Rate = Actual Variable OH/Actual hrs
= $6,800/3,360 hrs = $2.02381 per hour
Variable Overhead Rate Variance = (Std Rate - Actual Rate)*Actual Hrs
= ($3.50 - $2.02381)*3,360 hrs = $4,960 F
Variable Overhead Efficiency Variance = (Std hrs - Actual hrs)*Std Rate
= (3,040 hrs - 3,360 hrs)*$3.50 per hour = ($1,120) U
