The direct labor standards for a particular product are 4 hours of direct labor at $12.00 per direct labor-hour = $48.00. During October, 3,350 units of this product were made, which was 150 units less than budgeted. The labor cost incurred was $159,786 and 13,450 direct labor-hours were worked. The direct labor variances for the month were:   Labor Rate Variance Labor Efficiency Variance A) $1,614 U $600 U B) $1,614 U $600 F C) $1,614 F $600 U D) $1,614 F $600 F

Haylock Incorporated bases its manufacturing overhead budget on budgeted direct labor-hours. The direct labor budget indicates that 5,600 direct labor-hours will be required in August. The variable overhead rate is $5.40 per direct labor-hour. The company’s budgeted fixed manufacturing overhead is $69,440 per month, which includes depreciation of $15,680. All other fixed manufacturing overhead costs represent current cash flows. The August cash disbursements for manufacturing overhead on the manufacturing overhead budget should be:
