Nate multiplied 4×989

To estimate the product of \( 4 \times 989 \), we can round \( 989 \) to a nearby number that is easier to work with.

A reasonable rounding would be to:

- Round \( 989 \) down to \( 900 \).

Using this estimate:

\[ 4 \times 900 = 3,600 \]

Let's consider the options:

- \( 4 \times 900 = 3,600 \) (this fits our estimate)
- \( 5 \times 1,000 = 5,000 \) (too high)
- \( 4 \times 1,000 = 4,000 \) (too high)
- \( 5 \times 900 = 4,500 \) (this is also higher than our estimate)

The best option for a reasonable estimate of \( 4 \times 989 \) is:

**\( 4 \times 900 = 3,600 \)**.
