14. Nakamura Corporation had the following static budget: Units Revenues Direct materials 100,000 $18,000,000 2,500,000 4,000,000 6,000,000 Direct labor Variable overhead Fixed costs 5,000,000 Nakamura actually sold 120,000 units. Nakamura's standard price for direct materials is $12.50 per pound, standard price for direct labor is $8 per hour, and standard rate for variable overhead is 150% of direct labor costs. Nakamura actually earned $20,000,000 in revenues, spent $3,500,000 for 250,000 pounds of materials, spent $4,500,000 for 565,000 direct labor hours, and spent $6,500,000 on variable overhead and $5,500,000 on fixed costs. a. Calculate all nine variances and indicate whether they are favorable or unfavorable. b. Recalculate the variable overhead efficiency and spending variances if variable over- head is applied at a rate of $12.00 per direct labor hour. c. Recalculate the variable overhead efficiency and spending variances if variable over- head is applied at a rate of 240% of direct materials costs. d. Recalculate the variable overhead efficiency and spending variances if variable over- head is applied at a rate of $60 per unit.
