Answer:
Bradford's estimated variable manufacturing overhead cost is $127,200
Step-by-step explanation:
The cost function=$83,000+$12M
where M stands for machine hours required to produce the expected output in the month under review.
Each one-six unit case of Bradford's single product requires two machine hours,hence 5,300 cases would require 10,600 hours(5,300*2hrs).
Total estimated variable manufacturing overhead=cost per machine hour*expected number of machine hours
cost per machine hour is $12 as seen in the cost function
estimated variable manufacturing overhead=$12*10,600=$127,200
