Answer:
The $631,090 is the manufacturing overhead that would have been applied to all jobs during the period.

For computing the amount of manufacturing overhead, the calculation is shown below
= Actual machine hours × Predetermined overhead rate
= 28,300 × $22.30
= $631,090
Other cost like fixed manufacturing overhead, fixed machine hours, actual manufacturing overhead is not to be considered because these cost are considered in computing the predetermined overhead rate. But it is already given in the question. And some cost are irrelevant.
Thus, the $631,090 is the manufacturing overhead that would have been applied to all jobs during the period.
