Required: 1. Calculate the total cost of purchases for October. 2. Compute the direct materials price variance based on the actual quantity purchased. 3. Calculate the direct materials quantity variance based on the actual quantity used. 4. Compute the standard direct labor rate for October. 5. Compute the direct labor efficiency variance for October. Calculate the total cost of purchases for October. 2. Compute the direct materials price variance based on the actual quantity purchased. Note: Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). 3. Calculate the direct materials quantity variance based on the actual quantity used. Note: Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Compute the standard direct labor rate for October. Note: Round your answer to 2 decimal places. Compute the direct labor efficiency variance for October. Note: Round your intermediate calculation to 2 decimal places. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance)
