I think it’s B.25 because
If you round 47 it will be 50.Then you multiple 50 and 10 which you get 500.After you need to round 24 which is 20.When you do that you divide 500 and 20 which you get 25.

2. Answer:    Option B -25 bags.
consider – Round each amount to the nearest ten to find a reasonable estimate for the number of bags of marbles
We have been given that
No. of kids =47
After rounded its nearest ten then
No. of kids =50
Same as no. of marbles in a bag = 24
After  rounded its nearest ten = 20
No. of each player have marbles = 10
So, using the given information and calculating we have:
Total No. of marbles =  50× 10 = 500 marbles
We know that the total number of marbles needed is 500 marbles, so, calculating how many bags will Nhia have to buy, we have:
No. of bags = (Total no. of marbles / marbles per bag)
No. of bags = 500/20
No. of bags =25
Hence, Nhia will have to buy 25 bags of marbles.
