Answer 2

Problem Analysis

We are given that a locksmith can make 16 parts in 4 hours. We need to determine how many parts the locksmith will make in 8 hours if they make one more part each hour than they did before.

Solution

To solve this problem, we can use a simple mathematical approach. We know that the locksmith can make 16 parts in 4 hours, which means they make 4 parts per hour. If they make one more part each hour, then in the first hour they will make 4 + 1 = 5 parts, in the second hour they will make 5 + 1 = 6 parts, and so on.

To find the total number of parts made in 8 hours, we can sum up the number of parts made in each hour.

Calculation

Here is the calculation:

- In the first hour: 5 parts - In the second hour: 6 parts - In the third hour: 7 parts - In the fourth hour: 8 parts - In the fifth hour: 9 parts - In the sixth hour: 10 parts - In the seventh hour: 11 parts - In the eighth hour: 12 parts

To find the total number of parts made in 8 hours, we add up the number of parts made in each hour:

5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 = 68

Therefore, the locksmith will make 68 parts in 8 hours if they make one more part each hour than they did before.

Answer

The locksmith will make 68 parts in 8 hours if they make one more part each hour than they did before.
