Answer:
total predetermined overhead rate = $29.84 per machine hours
so correct option is C) $29.84 per machine-hour
Step-by-step explanation:
given data
machine hours = 10,000
variable manufacturing overhead = $6.82
fixed manufacturing overhead = $230,200
to find out
predetermined overhead rate
solution
we know that here variable manufacturing overhead so
estimated fixed overhead rate will be
estimated fixed overhead rate =

estimated fixed overhead rate = $23.02 per machine hour
and
total predetermined overhead rate is here
total predetermined overhead rate = $6.82 + $23.02
total predetermined overhead rate = $29.84 per machine hours
so correct option is C) $29.84 per machine-hour
