(Do not round intermediate calculations. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable.) Direct Material Price Variance Direct Material Quantity Variance Drac Material Guan nog vantanoExplanation / Answer
Actual direct material cost per sq. ft. = Cost of plastic purchased and used / Number of square feet of plastic used
= 7,910,000 / 11,300,000
= 0.7
Direct Material price variance = (Actual price - Standard price) * Actual quantity
= (0.7 - 0.73) * 11,300,000
= 339,000 Favourable
Direct Material Quantity variance = (Actual quantity - Standard quantity) * Standard price
= [11,300,000 - (1,020,000*11)] * 0.73
= 58,400 Unfavourable
