The computation is shown below:
a. Material Price Variance is
= Actual Quantity × (Actual Rate - Standard Rate)
= 6000 × ($18000 ÷ 6000 - $4)
= $6,000 Favorable
b. Material Quantity Variance is
= Standard Rate × (Actual Quantity - Standard Quantity)
= $4 × (6000 - 5 × 1000)
= $4,000 (Unfavorable)
c. It is favorable as actual production is more than the normal monthly output
