Final answer:
The manufacturing overhead cost allocated to Product Y is $15,209, and the manufacturing overhead cost allocated to Product Z is $12,485.
Step-by-step explanation:
In order to determine how much manufacturing overhead cost is allocated to Product Y and Product Z, we need to calculate the allocation using the plantwide overhead rate.
First, we need to calculate the plantwide overhead rate by dividing the total manufacturing overhead cost by the total estimated direct labor-hours.
Plantwide overhead rate = Total manufacturing overhead cost / Total estimated direct labor-hours
= $674,000 / 296,400 direct labor-hours
= $2.27 per direct labor-hour
Next, we can allocate the manufacturing overhead cost to each product using the plantwide overhead rate and their respective direct labor-hours.
Manufacturing overhead cost allocated to Product Y = Plantwide overhead rate * Direct labor-hours of Product Y
= $2.27 * 6,700 direct labor-hours of Product Y
= $15,209
Manufacturing overhead cost allocated to Product Z = Plantwide overhead rate * Direct labor-hours of Product Z
= $2.27 * 5,500 direct labor-hours of Product Z
= $12,485
Therefore, Product Y is allocated $15,209 of manufacturing overhead cost, while Product Z is allocated $12,485 of manufacturing overhead cost.
