ome work ( Check my worle Nolan Mills uses a standard cost system. During May, Nolan manufactured 15,000 pillowcases, using 27,600 yards of fabric costing $3.05 per yard and incurring direct labor costs of $17,172 for 3,180 hours of direct labor. The standard cost per pillowcase assumes 1.75 yards of fabric at $3.10 per yard, and 0.20 hours of direct labor at $5.95 per hour. a. Compute both the price variance and quantity variance relating to direct materials used in the manufacture of pillowcases in May. b. Compute both the rate variance and efficiency variance for direct labor costs incurred in manufacturing pillowcases in May. (For all requirements, Indicate the effect of each variance by selecting "Favorable" or "Unfavorable". Select "None" and enter "O" for no effect (i.e, zero variance). Round your answers to 2 decimal places.) a. Materials price variance Materials quantity variance b. Labor rate variance Labor efficiency variance
