Question

Problem 11-1A Rogen Corporation manufactures a single product. The standard cost per unit of product is shown below. $ 6.00 5.98 3.00 5.00 $19.98 Direct materials-1 pound plastic at $6 per pound Direct labor-0.50 hours at $11.95 per hour Variable manufacturing overhead Fixed manufacturing overhead Total standard cost per unit The predetermined manufacturing overhead rate is $16 per direct labor hour ($8.00 ÷ 0.50). It was computed from a master manufacturing overhead budget based on normal production of 2,600 direct labor hours (5,200 units) for the month. The master budget showed total variable costs of $15,600 ($6.00 per hour) and total fixed overhead costs of $26,000 ($10.00 per hour). Actual costs for October in producing 3,000 units were as follows. Direct materials (3,190 pounds) Direct labor (1,390 hours) Variable overhead $ 19,459 17,167 18,238 7,562 $62,426 Fixed overhead Total manufacturing costs The purchasing department buys the quantities of raw materials that are expected to be used in production each month. Raw materials inventories, therefore, can be ignored Compute all of the materials and labor variances. (Round answers to 0 decimal places, e.g. 125.) Compute all of the materials and labor variances. (Round answers to O decimal places, e.g. 125 Total materials variance Materials price variance Materials quantity variance Total labor variance Labor price variance Labor quantity variance Compute the total overhead variance.

Answer 1

a) Total materials variance (AQxAP) (SQ x SQ) Total Materials Variance (3,190 x $6.10)-( 3,000 x $6.00) - $19,459-$18,000 $1,459 U 3,000 x 1 3,000 SQ of Materials. Materials price variance (AQx AP) (AQ x SP) Material Price Variance (3,190 x $6.10)-(3,190 x $6.00) - $19,459 $19,140 $319 U Materials quantity variance (AQx SP) (SQ x SP) Materials Quantity Variance (3,190 x $6.00)-(3,000 x $6.00) - $19,140 $18,000 $1,140 U Total labor variance (AHX AR) (SH X SR) (1,390 x $12.35)-( 1,500x $11.95) - $17,167-$17,925 $758 F *3,000 x 0.50 Labor price variance AHX AR) (AH X SR) (1,390 x $12.35)-(1,390 x $11.95) = $17,167-$16,611=$556 U Labor quantity variance (AHX SR) (SHX SR) (1,390 x $11.95)-(1,500 x $11.95) - $16,611 $17,925 $1,314 F

b) Total overhead variance Actual Overhead-Overhead Applied ($18,238+$7,562)-(1,500 x $16*) $1,800 u *(S6 variable costs + $10 fixed overhead costs= $16)
