Answer:
It's reasonable.
Explanation:
To round to the nearest number we have to follow certain rules:
- If the number end in a digit between 1 and 49, we round to the lower number that ends in 00.
- If the number ends in 50 or more, we round to the higher next even hundred.
In this case, 3402 is rounded to 3400, and 4950 is rounded to 5000, if we sum these rounded numbers we have 3400 + 5000 = 8400.
No, Dalton has 8352 as a result, which is rounded to 8400. This means that Dalton's operation is reasonable. Actually, 8352 is the exact result of the sum.
