Final answer:
The budgeted variable overhead cost rate per output unit is $122.50. Correct option is B.
Step-by-step explanation:
The budgeted variable overhead cost rate per output unit can be calculated by dividing the budgeted variable manufacturing overhead costs by the budgeted output units. In this case, the budgeted variable manufacturing overhead costs for 730 loads is $89,425. Dividing this by 730 loads gives us a rate of approximately $122.85. Therefore, the correct answer is B) $122.50.
