Answer:
Variance is favorable when Standard quantity/ price is higher than actual quantity/ price.
a. Direct Materials Price Variance
= (Actual price - Standard price) * Actual quantity
= (5.70 - 6.00) * 51,000
= $15,300 Favorable
b. Direct Materials Quantity Variance
= (Actual quantity - Standard quantity) * Standard price
= (51,000 - (14 * 3,500)) * 6
= $12,000 Unfavorable
C. Direct Materials Cost Variance
= Direct Materials Price Variance + Direct Materials Quantity Variance
= 15,300 + (-12,000)
= $3,300 Favorable
