The total sales value of four products that are sold in a shop over a three year period is shown in the bar graph.
Soaps and hand wash had the highest sales value in all three years starting at $150,000 in 2010, going up an additional 30,000 the following year and ending up at $190,000 in 2012. Similarly, the annual total sales value for shower gels follows an upward trend from about $70,000 in 2010 to $110,000 two years later.
In the case of shampoos and hair conditioners the sales value in 2010 was the same at $70,000. In the next year shampoo went up to $80,000 while hair conditioners dropped to $60,000. 2012 saw a drop in the sales value of shampoo to $60,000 whereas hair conditioner's value stood a little below $80,000.
To sum up, soaps and hand wash had the greatest sales value in the three year period. The remaining three products value was much less and in 2010 these three products were at the same levels.
