Final answer:
The total cost of the inventory purchased by Allied is found by multiplying the quantity of units by the price per unit, which results in a total cost of $9,000.
Step-by-step explanation:
To calculate the total cost of the inventory purchased by Allied, we will multiply the quantity of units purchased by the cash price per unit. In this case, Allied made a purchase of 1,000 units at a price of $9 per unit. Therefore, the total cost is calculated as follows:
Total Cost = Quantity of Units Purchased × Cash Price Per Unit
Total Cost = 1,000 units × $9/unit
Total Cost = $9,000
Thus, the correct answer to the total cost of the inventory purchased by Allied is option 1) $9,000.
