Answer:
1. Plant wide predetermined overhead rate is $19 per hour
2. Manufacturing cost assigned to job P90 is $4,323
Step-by-step explanation:
1. In order to calculate the predetermined overhead rate based on machine hours expended, the fixed overhead cost would have to be divided by the machine hours and then add up variable overhead cost per machine hour
= [ Fixed manufacturing overhead / Machine hours required to support production ] + Variable manufacturing overhead cost per machine hour
= [$3,655,000/215,000] + $2
= $17 + $2
= $19 per hour
2. Manufacturing cost of job P90
Direct materials
$1,610
Direct labor cost
$1,155
Overhead 82 machine hours × $19
$1,558
Total cost
$4,323
