Coral 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 July exist. Coral knows that the total direct labor variance for the month was $390 F and that the standard labor rate was $9 per hour. A recent pay cut caused a favorable labor rate variance of $0.50 per hour. The standard direct labor hours for actual July outputs were 5,200. Compute and evaluate direct labor vacancies.

Answer:

Explanation:

std rate  $9.00

actual rate  $8.50

standard hours 5,200

Total variance: 390 Favorable

Rate variance:

[tex](standard\:rate-actual\:rate) \times actual \: hours = DL \: rate \: variance[/tex]

Efficiency

[tex](standard\:hours-actual\:hours) \times standard \: rate = DL \: efficiency \: variance[/tex]

Total:

rate + efficiency

[tex](standard\:rate-actual\:rate) \times actual \: hours + (standard\:hours-actual\:hours) \times standard \: rate = 390[/tex]

We plug our know values and solve:

[tex](9 - 8.5) \times actual \: hours + (5,200-actual\:hours) \times 9 = 390[/tex]

0.5actual hours + 46,800 - 9actual hours = 390

46,800 - 390 = 8.5 actual hours

46,410/8.5 = actual hours = 5,460

now we calculate each variance:

rate: 2,730

[tex](9-8.5) \times 5,460 = DL \: rate \: variance[/tex]

efficiency (2,340)

[tex](5,200-5,460) \times 9 = DL \: efficiency \: variance[/tex]
