Answer:
a. <u>Labor variances for 14 PT staff:
</u>
Labor rate variance = (Standard Rate – Actual Rate) x (Actual time per app) * (number of apps. completed)
= ($50 - $52) x 1.40 x 2,604
= $7291.20 (Unfavorable)
Labor Efficiency variance = [(Standard hours per app. X number of app.) - (Actual time per App. * number of apps.)] * Std. rate
= [(1.20 * 2,604) - (1.40 * 2,604)] * $50
= [3,124.80 - 3,645.60] * $50
= $26,040 (Unfavorable)
Labor Cost variance = Labor rate variance + Labor efficiency variance
= $7,291.20 (Unfavorable) + $ 26,040 (Unfavorable)
= $33,331.20 (Unfavorable)
<u>Labor variances for 10 SD staff</u>:
Labor rate variance = (Standard Rate – Actual Rate) x (Actual time per app) * (number of apps. completed)
= ($45 - $47) * 1.20 * 1,600
= $3840 (Unfavorable)
Labor Efficiency variance = [(Standard hours per app. X number of app.) - (Actual time per App. * number of apps.)] * Std. rate
= (1.40*1,600) – (1.20*1,600)]*$45
= [2,240 – 1,920] * $45
= $14,400 (Favorable)
Labor Cost variance = Labor rate variance + Labor efficiency variance
= $3,840 (Unfavorable) + $ 14,400 (Favorable)
= $10,560 (Favorable)
