An entity has 8,000 units in inventory on January 1, valued at 10 per unit. During the year,
the entity sold 25,000 units and purchased inventory as follows:

.......................Quantity

Date .................Purchased .........Unit Price

April 1 ..............15,000 units...... $ 8

July 1 ...............10,000 units .........9

October 1.......... 12,500 units........ 10

If the entity uses the weighted-average method of inventory valuation, cost of goods sold for
the period will be

Answer (C) is correct.
Under the weighted-average method, the weighted-average cost per unit
is multiplied by the number of units sold to determine the cost of goods
sold for the period. The total units available for sale equaled 45,500
(8,000 + 15,000 + 10,000 + 12,500). The total cost of all units available
for sale was $415,000 [(8,000 × $10) + (15,000 × $8) + (10,000 × $9) +
(12,500 × $10)]. Thus, the weighted-average cost per unit of inventory
was $9.1209 ($415,000 ÷ 45,500), and cost of goods sold was $228,023
(25,000 × $9.1209).
