The Sullivan Corporation manufactures lamps. It has set up the following standards per finished unit for direct materials and direct manufacturing labor:

Direct materials: 10 lb. at $4.70 per lb. $47.00
Direct manufacturing labor: 0.5 hour at $30 per hour 15

The number of finished units budgeted for January 2014

was 10,090; 9,950 units were actually produced.

Actual results in January 2014

were as follows:

Direct materials: 99,000 lb. used
Direct manufacturing labor: 4,800 hours	$152,400

Assume that there was no beginning inventory of either direct materials or finished units. During the month, materials purchases amounted to 100,900 lb., at a total cost of $494,410.

Input price variances are isolated upon purchase. Input-efficiency variances are isolated at the time of usage.
