Required information [The following information applies to the questions displayed below.] Trini Company set the following standard costs per unit for its single product. Overhead is applied using direct labor hours. The standard overhead rate is based on a predicted activity level of 80% of the company's capacity of 60,000 units per quarter. The following additional information is available. During the current quarter, the company operated at 90% of capacity and produced 54,000 units; actual direct labor totaled 265,000 hours. Units produced were assigned the following standard costs. Direct materials (1,620,000 pounds @ \$4 per pound) $6,480,000 Direct labor (270,000 hours @ \$14 per hour) Overhead (270,000 hours @ \$18 per hour) 3,780,000 Standard (budgeted) cost Actual costs incurred during the current quarter follow. Direct materials (1,615,000 pounds @ $4.10 per pound) $6,621,500 Direct labor (265,000 hours @ \$13.75 per hour) Fixed overhead Variable overhead Actual cost Required: (a) Compute the variable overhead spending and efficiency variances.
