Answer:
$11,000
Step-by-step explanation:
Fabricating Department budgeted direct labor = $9,280
Depreciation remains constant at any level of production.
Budgeted labor rate = Budgeted direct labor ÷ Hours of production
 = $9,280 ÷ 640
 = $14.5 per hour
Direct labor cost = completed hours of production × Budgeted labor rate
 = 600 × $14.5
 = $8,700
Budget for the Fabricating Department at 600 hours of production:
Budgeted cost = Direct labor cost + Equipment depreciation
 = $8,700 + $2,300
 = $11,000
