Answer:
Total Direct Materials Cost Variance = Direct Material Price Variance + Direct Material Quantity Variance
Total Direct Materials Cost Variance = $5,600U + (-$2,800F)
Total Direct Materials cost Variance = $2,800 Unfavorable
Direct Material cost Variance = (Actual rate * Actual quantity) - (Standard Rate * Standard Quantity)
$2,800 U = (AR*56000) - (SR * (15,000*5)
$2,800 U = (AR*56000) - (SR * 75000)
We need Standard Price per Gallon to calculate the actual price paid for a gallon of direct material. But, we have no information about it.
