Answer:
See below
Step-by-step explanation:
1. Total materials variance
= (Actual quantity - Actual price) - (Standard quantity × Standard price)
= $4,410 - [(160 × 9) × $1.9]
= $4,140 - $2,736
= $1,404 unfavorable
2. Materials price variance
= (Actual quantity × Actual price) - (Actual quantity × Standard price)
= $4,140 - (2,100 × $1.9)
= $4,140 - $3,990
= $150 unfavorable
3. Materials quantity variance
= (Actual quantity × Standard price) - (Standard quantity × Standard price)
= (2,100 × $1.9) - [(160 × 9) × $1.9]
= $3,990 - $2,736
= $1,254 unfavorable
4. Total labor variance
= (Actual hours × Actual rate) - (Standard hours - Standard rate)
= $6,664 - (160 × 4) × $10
= $6,664 - $6,400
= $264 unfavorable
