Answer:
The correct answer is 783 kg.
Explanation:
To solve this problem, we first must simply add all three values together. We can perform this operation because all three values have the same units of kilograms.
When we add, we get:
258.3 + 271.23 + 253 = 782.53 kg
However, this answer does not have the correct number of significant digits. When adding and subtracting values, we round our final answer to the least amount of decimal places of the numbers we were adding. In this case, that is 0 decimal places, because 253 doesn’t have a decimal place.
Therefore, we should round 782.53 to the ones place. Since the next number is a 5, we round up.
This gives us 783 kg, which is our final answer.
