Answer:
silver
direct materials price variance = $1,050 favorable
direct materials quantity variance = $13,200 favorable
Crystals
direct materials price variance = $671 favorable
direct materials quantity variance =$1,327.50 favorable
direct labor
direct materials rate variance = $1,200 unfavorable
direct materials efficiency variance =$2,100 favorable
Explanation:
silver
direct materials price variance = (Aq×Ap)-(Aq×Sp)
= (350×$21,00)-(350×$24.00)
= $1,050 favorable
direct materials quantity variance = (Aq×Sp)-(Sq×Sp)
= (350×$24.00) -(1,500×0,60×$24.00)
= $13,200 favorable
Crystals
direct materials price variance = (Aq×Ap)-(Aq×Sp)
= (3,050×$0,23)-(3,050×$0.45)
= $671 favorable
direct materials quantity variance = (Aq×Sp)-(Sq×Sp)
= (3,050×$0.45) -(1,500×4.00×$0.45)
= $1,327.50 favorable
direct labor
direct materials rate variance = (Aq×Ap)-(Aq×Sp)
= (2,400×$14,50)-(2,400×$14.00)
= $1,200 unfavorable
direct materials efficiency variance = (Aq×Sp)-(Sq×Sp)
= (2,400×$14.00) -(1,500×1.50×$14.00)
= $2,100 favorable
