1. Problem Description

The problem asks us to determine how many more pumpkins have a mass between 9 and 12 kg than between 0 and 3 kg, based on the provided bar graph.

2. Solution Steps

First, we need to read the number of pumpkins with mass between 9 kg and 12 kg from the graph. The bar corresponding to the mass range of 9-12 kg shows 6 pumpkins.

Next, we need to read the number of pumpkins with mass between 0 kg and 3 kg from the graph. The bar corresponding to the mass range of 0-3 kg shows 4 pumpkins.

Finally, we subtract the number of pumpkins in the 0-3 kg range from the number of pumpkins in the 9-12 kg range to find the difference.

$6 - 4 = 2$
