Answer and Explanation:
The computation is shown below:
1.
Direct Material Price Variance = Actual material cost - Actual Quantity × Standard Price
For Silver
= $13848 - 577 × 23
= $577 (U)
For Crystal
= $2926 - 7700 × 0.40
= $154 (F)
Direct Material Quantity Variance = (Actual Quantity - Standard Quantity) × Standard Price
For Silver
= (577 - 1530 × 0.40) × 23
= $805 (F)
For Crystal
= (7700 - 1530 × 5) × 0.40
= $20 (U)
2.
Direct Labor Rate Variance = Actual Cost - Actual Hours × Standard Rate
= $36915 - 3210 × 12
= $1605 (F)
And,
Direct Labor efficiency Variance = (Actual hours - Standard hours) × Standard Rate
= (3210 - 1530 × 2) × 12
= $1800 (U)
