22400 because the rule for rounding is to round based off of the number next to the place you want to round to. You're rounding to the nearest hundreds so you look at the tens place. If the number is 4 or less you round down, and if the number is 5 or more, you round up. The number in the tens place is 6 so you round up to get 22400. Hope that this answer and explanation help!
First convert the days to a week so 6000*7= 42000
So 42000 pounds a week : ____ tons a week. Since 1 ton is 2000 pounds you divide 42000 by 2000 which would be 21
So 6000 pounds a day is : 21 tons a week
