Answer:
$820
Step-by-step explanation:
Firstly, we need to find the overhead cost.
Overhead cost = 15 hours × $18
= $270 per hour
Labor cost = $15 hours × $12
= $180 per hour
Direct material = $370.
Therefore,
Total cost = $370 + $270 + $180
= $820
Total cost that should be assigned to the job is $820
