Some of my cousins and I spent a week helping Grandma Rosie clean out her attic. We found a bunch of marbles that she had collected as a child, and she told us we could split them among all the grandkids! We counted 3672 marbles in all, so each of us got a lot of marbles. But then we remembered that the Brewers, who had five of the grandchildren, weren’t with us. That meant each of those of us present had to give up 90 marbles, so that all the grandchildren would have the same number of marbles. How many grandchildren does Grandma Rosie have?
