Answer 2

Problem Statement

A locksmith makes 125 parts per day, while his apprentice makes 113 parts per day. They received an order for 4,500 parts. How many parts will they have left to make after 15 days of work?

Solution 1: Calculation

To solve this problem, we can calculate the total number of parts made by the locksmith and the apprentice in 15 days and subtract it from the total order of 4,500 parts.

The locksmith makes 125 parts per day, so in 15 days, he will make 125 * 15 = 1,875 parts.

The apprentice makes 113 parts per day, so in 15 days, he will make 113 * 15 = 1,695 parts.

Together, they will make a total of 1,875 + 1,695 = 3,570 parts in 15 days.

To find the number of parts they will have left to make, we subtract the total parts made from the total order: 4,500 - 3,570 = 930 parts.

Therefore, after 15 days of work, they will have 930 parts left to make.

Solution 2: Algebraic Approach

Alternatively, we can solve this problem using algebraic equations.

Let's assume the number of parts made by the locksmith in 15 days is L, and the number of parts made by the apprentice in 15 days is A.

According to the problem, the locksmith makes 125 parts per day, so in 15 days, he will make 15 * 125 = 1875 parts.

Similarly, the apprentice makes 113 parts per day, so in 15 days, he will make 15 * 113 = 1695 parts.

Therefore, we have the following equations: L = 1875 A = 1695

To find the number of parts they will have left to make, we subtract the total parts made from the total order: 4500 - (L + A).

Substituting the values of L and A, we get: 4500 - (1875 + 1695) = 4500 - 3560 = 930 parts.

Therefore, after 15 days of work, they will have 930 parts left to make.

Conclusion

After 15 days of work, the locksmith and his apprentice will have 930 parts left to make.

Problem Statement

A locksmith makes 125 parts per day, while his apprentice makes 113 parts per day. They received an order for 4,500 parts. How many parts will they have left to make after 15 days of work?

Solution 1: Calculation

To solve this problem, we can calculate the total number of parts made by the locksmith and the apprentice in 15 days and subtract it from the total order of 4,500 parts.

The locksmith makes 125 parts per day, so in 15 days, he will make 125 * 15 = 1,875 parts.

The apprentice makes 113 parts per day, so in 15 days, he will make 113 * 15 = 1,695 parts.

Together, they will make 1,875 + 1,695 = 3,570 parts in 15 days.

To find the number of parts remaining to be made, we subtract the total parts made from the total order: 4,500 - 3,570 = 930 parts.

Therefore, after 15 days of work, they will have 930 parts left to make.

Solution 2: Algebraic Approach

Alternatively, we can solve this problem using algebraic equations.

Let's represent the number of parts made by the locksmith in 15 days as L and the number of parts made by the apprentice in 15 days as A.

We know that the locksmith makes 125 parts per day, so L = 125 * 15.

Similarly, the apprentice makes 113 parts per day, so A = 113 * 15.

The total number of parts made in 15 days is the sum of L and A: L + A.

Substituting the values, we have L + A = (125 * 15) + (113 * 15).

Simplifying the equation, we get L + A = 1,875 + 1,695 = 3,570.

Therefore, the total number of parts made in 15 days is 3,570.

To find the number of parts remaining to be made, we subtract the total parts made from the total order: 4,500 - 3,570 = 930 parts.

Thus, after 15 days of work, they will have 930 parts left to make.

Conclusion

After 15 days of work, the locksmith and his apprentice will have 930 parts left to make out of the total order of 4,500 parts.
