Good day I need assistance solving the below problem

Problem 23-5A (Part Level Submission) Hart Labs, Inc. provides mad cow disease testing for both state and federal governmental agricultural agencies. Because the company's 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 @ $1.40 per tube) $2.80 Direct labor (1 hour @ $32 per hour) 32.00 Variable overhead (1 hour @ $6.00 per hour) 6.00 Fixed overhead (1 hour @ $12.00 per hour) 12.00 Total standard cost per test $52.80 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 2017, when 1,400 tests were conducted, resulted in the following: Direct materials (2,884 test tubes) $3,547 Direct labor (1,456 hours) 45,136 Variable overhead 8,316 Fixed overhead 15,792 Monthly budgeted fixed overhead is $17,520. Revenues for the month were $91,000, and selling and administrative expenses were $3,600. (a) Compute the price and quantity variances for direct materials and direct labor. (Round answers to 0 decimal places, e.g. 5,275.) Materials price variance $ 490 Favorable Materials quantity variance 4 Labor price variance Labor quantity variance
