Task 1: Number of Eggs Used for Salad

To solve this problem, let's break it down step by step.

1. Grandma bought 2 dozen eggs, which is equal to 2 * 12 = 24 eggs. 2. Then she bought another dozen, which is equal to 1 * 12 = 12 eggs. 3. So, in total, she had 24 + 12 = 36 eggs. 4. After using some eggs for the salad, she had 1 dozen and 5 eggs left, which is equal to 1 * 12 + 5 = 17 eggs. 5. To find out how many eggs she used for the salad, we subtract the remaining eggs from the total number of eggs: 36 - 17 = 19 eggs.

Therefore, Grandma used 19 eggs for the salad.

Task 2: Number of Children Roller Skating Initially

To solve this problem, let's follow the given information.

1. Initially, there were 11 boys and 15 girls who went home, which gives us a total of 11 + 15 = 26 children. 2. After they left, 8 children stayed behind to skate. 3. Therefore, the initial number of children roller skating was 26 + 8 = 34 children.

So, initially, there were 34 children roller skating.
