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 Xiongnu tribe was China's main enemy at that time. The Chinese built the Great Wall to prevent them from entering and conquering China. Originally made up of shorter walls between factions, the wall was fortified and lengthened under the emperor Qin Shi Huang beginning in 221 BC.he most famous is the wall built between 200 BC - 220 BC by the first Emperor of China, Qin Shi Huang; little of it remains; it was much farther north than the current wall, which was built during the Ming Dynasty.
