Problem Analysis

The problem states that a carpenter repaired 22 chairs in three days. On the first day, he repaired 7 chairs, and on the second day, he repaired twice as many as on the first day. The task is to determine how many chairs the carpenter had left to repair on the third day.

Solution

Let's calculate the number of chairs repaired on the second day and then find out how many chairs were left for the third day.

1. Chairs Repaired on the Second Day: - Chairs repaired on the first day: 7 - Chairs repaired on the second day: 2 * 7 = 14

2. Chairs Left for the Third Day: - Total chairs repaired in three days: 7 (first day) + 14 (second day) = 21 - Chairs left for the third day: 22 - 21 = 1

So, the carpenter had 1 chair left to repair on the third day.

Verification

Let's verify the solution using the given information.

- The carpenter repaired 22 chairs in three days. - On the first day, he repaired 7 chairs. - On the second day, he repaired twice as many as on the first day, which is 2 * 7 = 14 chairs. - Therefore, the total chairs repaired in three days are 7 + 14 = 21 chairs. - The number of chairs left for the third day is 22 - 21 = 1 chair.

The solution aligns with the given information, and the calculation is correct.

Conclusion

The carpenter had 1 chair left to repair on the third day.
