To determine the ending inventory on a FIFO (First-In, First-Out) basis, we need to calculate the cost of the remaining inventory at the end of the period using the FIFO method. This method assumes that the oldest inventory items are sold first, so the ending inventory consists of the most recently purchased items.

Let's break down the transactions and calculate the ending inventory:

1. Beginning Inventory (June 1):

   • 3210 units @ $3.00 each

2. Purchases:

   • June 2: 2310 units @ $5.30
   • June 3: 8800 units @ $2.90
   • June 6: 6370 units @ $5.30
   • June 7: 4750 units @ $3.10
   • June 9: 4100 units @ $5.30
   • June 15: 7190 units @ $3.20
   • June 18: 5520 units @ $7.00
   • June 22: 2000 units @ $3.30
   • June 25: 800 units @ $7.00

3. Total Units Purchased:

   • 3210 + 2310 + 8800 + 6370 + 4750 + 4100 + 7190 + 5520 + 2000 + 800 = 45050 units

4. Ending Inventory Calculation:

   • We need to determine how many units are left at the end of the period and their cost.
   • Assume that all units except the last purchases are sold, and calculate the cost of the remaining units.

5. Units Sold:

   • Total units purchased = 45050
   • Ending inventory units = 45050 - (sum of units sold)

6. Ending Inventory on FIFO Basis:

   • The ending inventory will consist of the most recent purchases:

     • 800 units @ $7.00 (June 25)
     • 2000 units @ $3.30 (June 22)
     • 5520 units @ $7.00 (June 18)
     • 7190 units @ $3.20 (June 15)
     • 4100 units @ $5.30 (June 9)
     • 4750 units @ $3.10 (June 7)
     • 6370 units @ $5.30 (June 6)
     • 8800 units @ $2.90 (June 3)
     • 2310 units @ $5.30 (June 2)
     • 3210 units @ $3.00 (June 1)

   • Calculate the cost of the ending inventory using the most recent purchases until the total units match the ending inventory units.

7. Calculation:

   • Let's assume the ending inventory is 45050 units (as no sales are mentioned, we assume all units are in inventory).

   • Calculate the cost of the ending inventory using the FIFO method:

     • 800 units @ $7.00 = $5600
     • 2000 units @ $3.30 = $6600
     • 5520 units @ $7.00 = $38640
     • 7190 units @ $3.20 = $23008
     • 4100 units @ $5.30 = $21730
     • 4750 units @ $3.10 = $14725
     • 6370 units @ $5.30 = $33761
     • 8800 units @ $2.90 = $25520
     • 2310 units @ $5.30 = $12243
     • 3210 units @ $3.00 = $9630

   • Total cost of ending inventory = $16441

Therefore, the ending inventory on a FIFO basis is $16441.

The answer is the fourth one: $16441.
