1. Perpetual Inventory Using LIFO

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

   Inventory		Purchases		Sales
   May 1	4,200 units at $31	May 10	2,100 units at $33	May 12	2,940 units
   		May 20	1,890 units at $35	May 14	2,520 units
   				May 31	1,260 units

   a. Assuming that the perpetual inventory system is used, costing by the LIFO 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 4. Under LIFO, if units are in inventory at two different costs, enter the units with the HIGHER unit cost first in the Cost of Merchandise Sold Unit Cost column and LOWER unit cost first in the Inventory Unit Cost column.
