Answer:
$1,143 favorable
Step-by-step explanation:
cost per month = $2,800 + $381 per day
budgeted costs for February = $2,800 + ($381 x 17 days) = $9,277
actual days worked during February 14
flexible budget = $2,800 + ($381 x 14) = $8,134
Activity variance = flexible budget costs - fixed budgeted costs = $8,134 - $9,277 = -$1,143 favorable
Activity variance measures the difference between a flexible budget and the fix budget.
