Answer:
The price variance is -$450 favorable
The quantity variance is $300 unfavorable
The Total direct materials cost variance is -$150 favorable
Step-by-step explanation:
According to given data we have the following:
standard price=$15
Actual price=$8,550/600=$14.25
standard quantity=580
Actual quantity=600
To calculate the price variance, quantity variance, and total direct materials cost variance for December we would have to make the following calculations:
price variance=(Actual price-standard price)*Actual quantity
price variance=($14.25-$15)*600
price variance=-$450 favourable
quantity variance=(Actual quantity-standard quantity)*standard price
quantity variance=(600-580)*$15
quantity variance=$300 unfavorable
total direct materials cost variance=materials price variance+material quantity variance
total direct materials cost variance=-$450+$300
total direct materials cost variance=-$150
