Answer:
D. $5.40 per direct labor-hour and $11,065
Explanation:
The computation of the total job cost is shown below
= Direct material cost + direct labor cost + direct labor hours × predetermined overhead rate
= $715 + $9,000 250 hours × $5.4
= $715 + $9,000 + $1,350
= $11,065
The predetermined overhead rate is come from
= Total fixed manufacturing overhead cost ÷ direct labor hours + variable manufacturing overhead cost per direct labor hours
= $160,000 ÷ 80,000 direct labor hours + $3.40
= $2 + $3.40
= $5.40
