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 Han government, however, did not have the resources to buy off all of the nomads. One of the most important factors in the collapse of the Han Dynasty, in fact, may have been the Sino-Xiongnu Wars of 133 BCE to 89 CE. For more than two centuries, the Han Chinese and the Xiongnu fought throughout the western regions of Chinaâa critical area that Silk Road trade goods needed to cross to reach the Han Chinese cities.
