Question 4

Suppose you have a collection of pebbles that you want to store in small boxes. If you put 9 in each box, 1 is left behind. If you put 8 each, 3 are left behind. If you put 11 instead, 3 are also left behind. Given that the total number of marbles you have is close to but does not exceed 100, how many do you have?
