The cost of the inventory remaining under the weighted average method is $224. Option B is correct.
To solve this problem
Firstly, let calculate the total cost of the units purchased:
2 units ×$50/unit+3 ×$60/unit =$100 +$180 =$280
Now, let calculate the total number of units purchased:
2units + 3 units = 5 units
Let's figure out the average price per unit:
Total cost / Total units equals the average cost per unit.
280/5 = $56/units
Let's now determine the remaining inventory's (4 units) cost:
4x $56/units =$224
So, the cost of the inventory remaining under the weighted average method is $224
