Auto Brakes Inc. manufactures brake rotors and has always applied overhead to production using direct labor hours. Recently, company facilities were automated, and the accounting system was revised to show only two cost categories: direct material and conversion. Estimated variable and fixed conversion costs for the current month were $68,000 and $30,400, respectively. Expected output for the current month was 2,000 rotors, and the estimated number of machine hours was 4,000. During July, the firm actually used 3,600 machine hours to make 1,920 rotors while incurring $91,200 of conversion costs. Of this amount, $60,000 was variable cost. Using the four-variance approach, compute the variances for conversion costs. Note: Do not use negative signs with your answers.
