A machine produces 2825 screws in a day. Which of the following is the best estimate of the number of screws to the nearest thousands ?

Options

A. 3500
B. 5000
C. 3000
D. 2900

Answer

To estimate the number of screws produced by the machine (2825) to the nearest thousand, follow these steps:

### Step-by-Step Solution:

1. **Identify the number**: The number of screws produced in a day is 2825.

2. **Locate the thousands place**: In the number 2825, the digit in the thousands place is 2 (which represents 2000).

3. **Look at the hundreds place**: The digit in the hundreds place is 8 (which represents 800).

4. **Determine if you round up or down**: To round to the nearest thousand, we need to look at the hundreds digit (8 in this case). If the hundreds digit is 5 or greater, we round up. If it is less than 5, we round down.

5. **Apply the rounding rule**: Since 8 is greater than 5, we round up the thousands place from 2 to 3.

6. **Write the estimated number**: Therefore, when rounded to the nearest thousand, 2825 becomes 3000.

### Final Answer:
The best estimate of the number of screws to the nearest thousand is **3000**.
