Answer:
allocate overhead for the job: 274,320
Step-by-step explanation:

we calculate the predeterminated rate based on the division between the expected overhead and the expected cost driver:
expected overhead cost: 266,400
expected machine hours: 18,500
rate: 266,400 / 18,500 = 14.4
applied overhead:
machine hours for the job x rate
19,050 x 14.4 = 274,320
