Nhia is setting up a marble tournament for the kids in her apartment complex. So far, 47 kids have signed up to play. Each player needs 10 marbles. Nhia found a discount store that sells bags of 24 marbles. Round each amount to the nearest ten to find a reasonable estimate for the number of bags of marbles Nhia will have to buy to be sure to have enough marbles.
