Answer:
(D) $555,750
Explanation:
The computation of the estimated direct cost is shown below:
= (Sales revenue - opening stock + beginning stock) × direct labor hours × direct labor wage rate
= ($11,100 - $4,440 + $5,040) × 2.5 hours × $19
= $11,700 × 2.5 hours × $19
= $555,750
The opening stock = August sales × given percentage
= $11,100 × 40%
= $4,440
The closing stock = September sales × given percentage
= $12,600 × 40%
= $5,040
