Answer:
$150,400.00 (U)
Explanation
First, calculate the standard hours (the hours of labor the work should have taken):
HOURS PREDICTED =
UNITS PRODUCED *
STANDARD LABOR PER UNIT2,200.00 = 2,000.00 * 1.10
Next, figure out how many hours more than the expected (standard) were used:
MORE HOURS THAN STANDARD =
HOURS SPENT -
HOURS PREDICTED18,800.00 = 21,000.00 - 2,200.00
Finally, multiply the result by the labor rate:
LABOR EFFICIENCY VARIANCE =
MORE HOURS THAN STANDARD *
LABOR COST PER HOUR$150,400.00 = 18,800.00 * $8
Because the variance is positive, the variance is considered unfavorable.
