V. Computation of materials, labor, and overhead variances Tuna Company set the following standard unit costs for its single product.

Direct materials (25lbs. @ $4 per lb.)	100.00
Direct labor (6 hrs. @ $8 per hr.)	48.00
Factory overhead - variable (6 hrs. @ $5 per hr.)	30.00
Factory overhead - fixed (6 hrs. @ $7 per hr.)	42.00
Total Standard Cost	220.00

The predetermined overhead rate is based on a planned operating volume of 80% of the productive capacity of 60,000 units per quarter. The following flexible budget information is available.

Operating Levels
	70%	80%	90%
Production in units	42,000	48,000	54,000
Standard direct labor hours	252,000	288,000	324,000
Budgeted Overhead
Fixed factory overhead	2,016,000	2,016,000	2,016,000
Variable factory overhead	1,260,000	1,440,000	1,620,000

During the current quarter, the company operated at 70% of capacity and produced 42,000 units of product; actual direct labor totaled 250,000 hours. Units produced were assigned the following standard costs:

Direct materials (1,050,000 lbs. @ $4 per lb.)	4,200,000
Direct labor (252,000 hrs. @ $8 per hr.)	2,016,000
Factory overhead (252,000 @ $12 per hr.)	3,024,000
Total Standard Cost	9,240,000

Actual costs incurred during the current quarter follow:

Direct materials (1,000,000 lbs @ $4.25)	4,250,000
Direct labor (250,000 hrs. @ 7.75)	1,937,500
Fixed factory overhead cost	1,960,000
Variable factory overhead cost	1,200,000
Total Actual Cost	9,347,500

1. Compute the direct materials cost variance, including its price and quantity variances. 2. Compute the direct labor variance, including its rate and efficiency variances. 3. Compute the overhead controllable and volume variances. 4. Compute the variable overhead spending and efficiency variance 5. Compute the fixed overhead spending and volume variance.
