Now we can calculate the cost of the sale by taking the average cost per unit multiplied by the number of units sold. Next, calculate the value of the remaining units. There are 125 units left. We will assign $8.03 per unit because that is the weighted average cost of those units on January 7.oods available for sale is 415 units with a total cost of $3,394.00. If we divide $3,394.00 by 415, we get a weighted average cost of $8.18 (rounded) per unit. The rest of the calculation is very simple at this point. The company sold 245 units.
In 111 BC, the Han dynasty of China conquered the Nam Viá»t (or Nanyue) kingdom during its expansion southward and incorporated what is now northern Vietnam, together with much of modern Guangdong and Guangxi , into the expanding Han empire.
The Qin rulers conquered all the other states and some surrounding regions. However, their dynastic rule from 221-206 BC was the shortest in the region's history. Their empire fell apart after only 15 years. In only 9 years in successive wars from 230 to 221, the Qin conquered every other region of the former Zhou Empire. Then the Qin conquered outlying regions to the south all the way to Vietnam and to the north towards Korea. They had the biggest empire in the region's history until then.
