Hart Labs, Inc. provides mad cow disease testing for both state and federal governmental agricultural agencies. Because the companys customers are governmental agencies, prices are strictly regulated. Therefore, Hart Labs must constantly monitor and control its testing costs. Shown below are the standard costs for a typical test.

Direct materials (2 test tubes @ $1.50 per tube)		$3.00
Direct labor (1 hour @ $31 per hour)		31.00
Variable overhead (1 hour @ $7.00 per hour)		7.00
Fixed overhead (1 hour @ $12.00 per hour)		12.00
Total standard cost per test		$53.00

The lab does not maintain an inventory of test tubes. As a result, the tubes purchased each month are used that month. Actual activity for the month of November 2020, when 800 tests were conducted, resulted in the following.

Direct materials (1,680 test tubes)		$2,352
Direct labor (824 hours)		24,720
Variable overhead		4,712
Fixed overhead		9,952

Monthly budgeted fixed overhead is $17,880. Revenues for the month were $52,000, and selling and administrative expenses were $4,600.
