Answer:
$540,000
Step-by-step explanation:
The amount on of variable manufacturing overhead cost to be included in the company's planning budget for March is budgeted production units of 20,000 units multiplied by standard direct labor hours of 3 hours per unit multiplied by cost of direct labor hour used for variable overhead which is $9.
budgeted variable overhead cost for March=20,000*3*$9=$540,000.00
However, the actual cost of variable manufacturing overhead for the month is $612,300,hence an adverse variance of $72,300 is recorded ($612,300-$540,000)
