Coral's Music manufactures harmonicas. Coral uses standard costs to judge performance. Recently, a clerk mistakenly threw away some of the records, and only partial data for December exists. Coral knows that the total direct labor variance for the month was $340 F and that the standard labor rate was $8 per hour. A recent pay cut caused a favorable labor price variance of $0.60 per hour. The standard direct labor hours for actual December outputs were 5,500. Part 1: Word Options for First Half and Second Half of Actual Direct Labor Rate Per Hour Formula: Part 2: Part 3: Word Options for Fill-in-the-Blank of DL rate variance formula and DL efficiency variance formula: Part 4: Do these variances suggest that the manager may have made trade-offs? Explain. The (favorable, unfavorable) direct labor rate variance combined with the (favorable, unfavorable) direct labor efficiency variance suggests that the manager may have used (higher-paid, more efficient or lower-paid, less efficient) workers. However, due to the overall net effect, it appears there was (a reasonable trade-off, no trade-off).
