Band 7+: The pie chart below displays the total sales by category for two locations. The East location and the West location. The sales are calculated in dollars.

The pie charts illustrate the value of four types of electronic items that are sold in two locations: the East location and the West location.

Overall, it is evident that although a significant proportion of cell phones are sold in both regions, the sale of mobile phones is the most in the Eastern area compared to the Western part. The sale of laptop in the East was the second highest. This trend changes and is replaced by desktop in the West. However, the distributions of software sales are the lowest not only in the Eastern region but also in the Western portion.

To begin with, one-fifth of cell phones are sold in the East. This amount is reduced by $2,500 to stand at exactly $17500 in the West. Likewise, the value of laptop sales is around $15,000 in the East, which is doubled of laptop sales of the West. By contrast, approximately 10% desktop is sold in the West, while in the west, its value stands at 12%. On the other hand, among the four items, the sales value of the software was the lowest in the East which constitutes around 7.5%, whereas the figure exhibits around 6% in the West.
