Cull Corporation uses a job-order costing system with a single plantwide predetermined overhead rate based on machine-hours. The company based its predetermined overhead rate for the current year on total fixed manufacturing overhead cost of $433,100, variable manufacturing overhead of $2.20 per machine-hour, and 61,000 machine-hours. The company has provided the following data concerning Job X455 which was recently completed: If the company marks up its unit product costs by 25% then the selling price for a unit in Job X455 is closest to: (Round your intermediate calculations to 2 decimal places.)

A) $406.75
B) $305.40
C) $76.35
D) $381.75

1) Calculation of predetermined overhead rate:
Fixed manufacturing overhead cost = $433,100
Variable manufacturing overhead cost per machine-hour = $2.20
Machine-hours = 61,000
Predetermined overhead rate = (Total fixed manufacturing overhead cost + Total variable manufacturing overhead cost) / Total machine-hours
= ($433,100 + ($2.20 x 61,000)) / 61,000
= $0.072 per machine-hour

2) Calculation of total manufacturing cost for Job X455:
Direct materials cost = $29,550
Direct labor cost = $23,640
Manufacturing overhead cost = Predetermined overhead rate x Machine-hours used
= $0.072 x 1,800 machine-hours
= $129.60
Total manufacturing cost = $29,550 + $23,640 + $129.60 = $53,319.60

3) Calculation of markup and selling price:
Markup = 25% of total manufacturing cost = 0.25 x $53,319.60 = $13,329.90
Selling price = Total manufacturing cost + Markup
= $53,319.60 + $13,329.90
= $66,649.50
Selling price per unit = Selling price / Number of units produced
= $66,649.50 / 174 units
= $383.63 (rounded to the nearest cent)
Therefore, the closest selling price for a unit in Job X455 is D) $381.75.
