2a) The following chart shows Pizza Sub Sales over a month. What 2 graphs would show the information accurately?

A line graph and bar graph.

2b) If you were selling Pizza Subs would you continue? How does your graph explain your answer.

If i was selling pizza subs I would continue because the line graph shows how much more I am selling.

4. Below you see 2 different examples of graphs showing healthy choices sold at the canteen. If you had to convince Mrs Mota that we should continue selling healthy choices which graph would you choose?

4a) Change each graph so that your information looks even MORE impressive. You may not change the data just the graphs
