Calculation of the Amount of Paper Collected by Third Graders

To calculate the amount of paper collected by the third graders, we need to consider the information provided about the first and second graders. Let's break down the information step by step:

1. The first graders collected 40 kg of paper. 2. The second graders collected 7 kg less than the first graders. 3. The third graders collected 12 kg more than the second graders.

To find the amount of paper collected by the third graders, we can follow these steps:

1. Subtract 7 kg from the amount collected by the first graders: 40 kg - 7 kg = 33 kg. 2. Add 12 kg to the amount collected by the second graders: 33 kg + 12 kg = 45 kg.

Therefore, the third graders collected 45 kg of paper.
