Answer 2

Problem Analysis

The shepherd initially had 7 dogs, and each dog consumed one loaf of bread per day. Later, the shepherd acquired one more dog that ate for three dogs but served as five dogs. The shepherd then gave away the extra dogs. We need to determine how many loaves of bread the shepherd saves daily.

Solution

Let's break down the problem step by step:

1. The shepherd initially had 7 dogs, and each dog consumed one loaf of bread per day. So the total number of loaves consumed by the 7 dogs is 7 loaves per day.

2. The shepherd acquired one more dog that ate for three dogs but served as five dogs. This means that the new dog consumes the same amount of bread as three dogs but provides the work of five dogs. Therefore, the shepherd effectively reduced the number of dogs by two (3 - 5 = -2).

3. The shepherd gave away the extra dogs. Since the shepherd had 7 dogs initially and gave away the extra dogs, we can calculate the number of remaining dogs as follows: 7 - 2 = 5 dogs.

4. Now, let's calculate the number of loaves of bread saved daily. Since each dog consumes one loaf of bread per day, the shepherd saves 2 loaves of bread per day for the two extra dogs that were given away.

Answer

The shepherd saves 2 loaves of bread daily.

Explanation

The shepherd initially had 7 dogs, each consuming one loaf of bread per day. After acquiring one more dog that ate for three dogs but served as five dogs, the shepherd effectively reduced the number of dogs by two. Therefore, the shepherd now has 5 dogs. Since each dog consumes one loaf of bread per day, the shepherd saves 2 loaves of bread daily for the two extra dogs that were given away.
