Answer: 3.5 - 4.4 pounds
Explanation:
You included no options so I answered with the range of the answer.
When rounding a number up to the nearest whole number, the number needs to have the first decimal being 0.5 and above all the way to 0.9.
When rounding a number down to the nearest whole number, the number needs to have its first decimal being 0.1 to 0.4 to be rounded down.
For instance, 3.5 to 3.9 would get rounded up to 4 pounds.
4.1 to 4.4 would be rounded down to 4 pounds.
