The predetermined manufacturing overhead application rate for the plant is $10.55 per machine hour, which is calculated by dividing the total fixed manufacturing overhead costs by the total machine hours.
To calculate the predetermined manufacturing overhead application rate for the plant, we need to add up the estimated fixed manufacturing overhead costs for both the assembly and painting departments.
For assembly, the fixed manufacturing overhead cost is estimated to be $9,000,000, and for painting, it is estimated to be $739,000. Adding these two amounts together gives us a total fixed manufacturing overhead cost of $9,739,000.
Next, we need to calculate the total machine hours for both departments. Assembly uses 881,000 machine hours, while painting uses 43,000 machine hours. Adding these two amounts together gives us a total of 924,000 machine hours.
Now, we can calculate the predetermined manufacturing overhead application rate by dividing the total fixed manufacturing overhead cost by the total machine hours. In this case, the rate would be:
$9,739,000 / 924,000 machine hours = $10.55 per machine hour.
So, the predetermined manufacturing overhead application rate for this plant is $10.55 per machine hour.
It's important to note that this rate is used to allocate manufacturing overhead costs to different products or jobs based on the machine hours they require. This rate helps determine the total manufacturing overhead cost associated with a specific product or job.
