XY Inc. provides the following data for June 2011 when 13,000 Units are manufactured:

Standard Material Cost (Per Unit) 6.20 kg @ $ 10.25/kg

Actual Material Cost (Per Unit) 6.85 kg @ $ 13.8/kg

Standard Labor cost (Per Unit) 5.5 hrs @ $ 14/hr

Actual Labor cost (Per Unit) 5.30 hrs @ $ 15.2 /hr

a) Calculate:

Direct Material Price Variance

Direct Material Quantity/Usage Variance Total Material Cost Variance

Direct Labor Rate Variance Direct Labor Efficiency Variance Total Labor Cost Variance

(b): Calculate Variable Overhead Spending Variance if actual labor hours used are 360, standard variable overhead rate is $11.40 per direct labor hour and actual variable overhead rate is $10.30 per direct labor hour. Also specify whether the variance is favorable or unfavorable.

(c): Calculate the variable overhead efficiency variance using the following figures:

Number of Units Produced	720
Standard Direct Labor Hours Per Unit	1.2
Actual Direct Labor Hours Used	360
Standard Variable Overhead Rate	$11.40
