Standard Direct Labor Rate per Hour $25.50 22.50 16.50 Standard Direct-Labor Hours Allowed, Given April Output 2,500 2,500 2,500 Labor class III Labor class II Labor class I A new union contract negotiated in March resulted in actual wage rates that differed from the standard rates. The actual direct-labor hours worked and the actual direct- labor rates per hour experienced for the month of April were as follows: Actual Direct- Labor Hours Actual Direct- Labor Rate per Hour $27.30 24.00 17.70 2,600 Labor class III Labor class II Labor class I 2,800 2,250 Required: 1-a.
