Solve the pictorial graph problem about crop bags, using the key that 1 box represents 12 bags.

Here are the solutions to the problems.

1. Pictorial Graph (Crops)
The key states that $\boxed{\text{1 box represents 12 bags}}$.
Let's calculate the number of bags for each crop:

• Maize: 7.5 boxes $\times$ 12 bags/box = 90 bags
• Rice: 5.5 boxes $\times$ 12 bags/box = 66 bags
• Beans: 4 boxes $\times$ 12 bags/box = 48 bags
• Potatoes: 6.5 boxes $\times$ 12 bags/box = 78 bags
• Onion: 3.5
