Respuesta :
a. Standard labor-hours is 7920 hours.
b. Standard labor cost allowed is $42,768.
c. The labor spending variance is $1588(U).
d. The labor rate variance is $1706 and the labor efficiency variance $3294(U).
e. The variable overhead rate is $5971(U) and efficiency variances for the month $5580(U).
Explanation:
a)Standars hours(SH) allowed to make 19800 jogging mates
=SH per unit [tex]\times[/tex] 19800
=(24/60)*19800
=7920 hours
24/60 has been taken to convert minutes into hours.
b)Standard Labor Cost (SC) of 19800 jogging mates
[tex]=19800 \times SC per unit=19800 \times $2.16\\=$42,768[/tex]
=$42,768
c)Labour Spending Variance
[tex]=Standard Cost - Actual Cost(AC)=$42,768 - $44,356=$1588(U)[/tex]
=$1588(U)
d)Labor Rate Variance
[tex]=(SR per hour-AR per hour)\timesAH=(5.4-5.2)*8530=$1706(F)[/tex]
=$1706
Actual Hours(AH) * Actual Rate per hour(AR)= Actual Cost(AC)
[tex]8530 \times AR = $44,356[/tex]
[tex]AR = \frac{44356}{8530}\\ \\AR = 5.2[/tex]
Labor Efficiency Variance
[tex]=(SH-AH) \times SR\\=(7920-8530)*$5.4=$3294(U)[/tex]
=$3294(U)
e) Variable overhead rate variance = Actual hours worked (Standard overhead rate - Actual overhead rate)
= 8530 (4.5 - 5.20)
= $5971(U)
Actual overhead rate = $44,356 / 8530 = 5.20
Variable overhead efficiency variance = Standard overhead rate (Standard hours - Actual hours)
= 4.50 (7290 - 8530)
= $5580(U).
