She has been provided with the following standard cost per swimming pool: During June, the plant produced 4,000 pools and incurred the following costs: a. Purchased 20,200 pounds of materials at a cost of $2.85 per pound. b. Used 15,000 pounds of materials in production. (Finished goods and work in process inventories are insignificant and can be ignored.) c. Worked 3,400 direct labor-hours at a cost of $7.60 per hour. d. Incurred variable manufacturing overhead cost totaling $10,260 for the month. A total of 2.700 machine-hours was recorded. It is the company's policy to close all variances to cost of goods sold on a monthly basis. Summarize the variances that you computed in requirement 1 by showing the net overall favorable or unfavorable variance for the month. (Indicate the effect of each variance by selecting "F" for favorable, " U " for unfavorable, and "None" for no. effect (i.e, zero variance). Input all amounts as positive values.)
