Question # 6:

A.) From the pictograph, Which fruit seems to sell the best? Explain
Apples, because their drawn bigger making it seem like it was sold more.

B.) Does it seem that more cherries were sold or more peaches? Explain.
It seems that more peaches were sold than cherries, because there were more cherries drawn than peaches. But looking at the diagram 2 cherries equal to 20kg. So if you compare the kilograms sold between cherries and peaches. 100kg were sold for peaches and 90kg sold for cherries. Meaning more peaches were sold.

C.) How should the pictograph be redrawn to represent the data more accurately?
It could be redrawn by making all the fruits the same size.
