Problem Analysis

To solve this problem, we need to find the total weight of sugar and grains brought to the school cafeteria. We are given that there are 5 packages of sugar, with each package containing 7 kg of sugar. Additionally, there are 5 packages of grains, with each package containing 2 kg more than the sugar packages.

Solution

Let's calculate the total weight of sugar and grains step by step:

1. Calculate the total weight of sugar: - Each package of sugar contains 7 kg. - There are 5 packages of sugar. - Therefore, the total weight of sugar is 5 * 7 kg = 35 kg.

2. Calculate the total weight of grains: - Each package of grains contains 2 kg more than the sugar packages. - Therefore, each package of grains contains 7 kg + 2 kg = 9 kg. - There are 5 packages of grains. - Therefore, the total weight of grains is 5 * 9 kg = 45 kg.

3. Calculate the total weight of sugar and grains: - The total weight of sugar is 35 kg. - The total weight of grains is 45 kg. - Therefore, the total weight of sugar and grains is 35 kg + 45 kg = 80 kg.

Answer

In total, 80 kg of sugar and grains were brought to the school cafeteria.
