Smith Music manufactures harmonicas. Smith uses standard costs to judge performance. Recently, a clerk mistakenly threw away some of the records, and only partial data for May exist. Smith knows that t total direct labor variance for the month was $330F and that the standard labor rate was $10 per hour. A recent pay cut caused a favorable labor rate variance of $0.50 per hour. The standard direct labor ho for actual May outputs were 5,600 Requirements 1. Find the actual number of direct labor hours worked during May. First, find the actual direct labor rate per hour. Then, determine the actual number of direct labor hours worked by setting up the computation of the total direct labor variance as given. 2. Compute the direct labor rate and efficiency variances. Do these variances suggest that the manager may have made trade-offs? Explain
