Answer: $9.20
Step-by-step explanation:
Using the weighted average inventory costing method, the price is abased on the number of units and their price.
The above inventory cost would be calculated as follows:
= [ (Opening units * Cost of units) + (Units purchased * Cost of purchase) ] / Total units in inventory
= [ (20 * 8) + (30 * 10) ] / (20 units + 30 units)
= [ 160 + 300 ] / 50
= $9.20
