Answer:
The correct option is D,25000 machine hours
Explanation:
Department 2 machine hours can be computed using the formula for plant-wide overhead rate, which is given below:
Plantwide overhead rate = Total Manufacturing Overhead /Total Machine hours
Plantwide overhead rate is given as $10
Total manufacturing overhead=$250000+$150000
=$400000
$10=$400000/Total Machine Hours
by cross-multiplication
Total machine hours=$400000/$10
Total machine hours is 40000 hrs
Total machine hours=machine hrs in Dept 1+machine hrs in dept 2
40000=15000+machine hrs in dept 2
Machine hrs in dept 2=40000-15000
Machine hrs in dept =25000 hrs
