Answer:
$108,000
Explanation:
Favorable rate variance arises when the actual cost is lower than the implied cost. Implied cost can be calculated by multiplying standard rate with actual hours.
Labor rate variance = Actual Labor cost - Implied Labour cost
Favorable Labor rate variance = Implied Labour cost - Actual Labor cost
Favorable Labor rate variance = (Standard rate x Actual hours) - Actual Labor cost
$12,000 = ($8 x (5 x 3000)) - Actual Labor cost
$12,000 = ($8 x 15,000) - Actual Labor cost
$12,000 = $120,000 - Actual Labor cost
Actual Labor Cost = $120,000 - $12,000 = $108,000
