Final answer:
The expected number of hours of direct labor for the OM362 is 11,200 hours of assembling and 22,400 hours of polishing, as each unit requires 1 hour of assembling and 2 hours of polishing to be produced. The correct option is B.
Step-by-step explanation:
To calculate the expected number of hours of direct labor for OM362, we use the information provided about the operations required for each unit. As stated, each OM362 unit requires one labor hour of assembling and two labor hours of polishing.
Shamokin Manufacturing plans to sell 10,000 units and expects to end with 2,000 units in inventory, which implies the production will be the sum of units sold and ending inventory minus the beginning inventory (10,000 + 2,000 - 800 = 11,200 units).
To find the total assembling hours, we multiply the number of units (11,200) by the hours required for assembling (1 hour), which results in 11,200 hours of assembling. For total polishing hours, we multiply the same number of units by the hours required for polishing (2 hours), yielding 22,400 hours of polishing.
Therefore, the expected number of hours of direct labor for OM362 is 11,200 hours of assembling and 22,400 hours of polishing, which corresponds to option B.
