Final answer:
The flexible-budget amount for variable manufacturing overhead is $285,625.
Step-by-step explanation:
The flexible-budget amount for variable manufacturing overhead can be calculated by multiplying the budgeted variable manufacturing overhead costs for 8,000 units by the actual machine-hours used, and then dividing by the budgeted machine-hours.
Formula: Flexible-Budget Amount = (Actual machine-hours used / Budgeted machine-hours) * Budgeted variable manufacturing overhead costs for 8,000 units
Using the given values, the calculation would be: (23,750 / 24,000) * $288,000 = $285,625
