1. Perpetual Inventory Using FIFO

   Beginning inventory, purchases, and sales data for prepaid cell phones for May are as follows:

   Inventory		Purchases		Sales
   May 1	1,800 units at $40	May 10	900 units at $42	May 12	1,260 units
   		May 20	810 units at $44	May 14	1,080 units
   				May 31	540 units

   Assume that the business maintains a perpetual inventory system, costing by the first-in, first-out method. Determine the cost of merchandise sold for each sale and the inventory balance after each sale, presenting the data in the form illustrated in Exhibit 3. Under FIFO, if units are in inventory at two different costs, enter the units with the LOWER unit cost first in the Cost of Merchandise Sold Unit Cost column and in the Inventory Unit Cost column.
