    word problem

    A postal worker has 600 houses on his route. During one snowy day, he noticed that every other house’s mailbox was blocked by snow, and he could not deliver the mail. He also noticed that he had no mail to deliver to every third house on the route. By the end of his route, how many households had mail that was still in his truck?

    re: word problem

    Start by thinking about what happens at the first six houses if you were the one delivering the mail.

    Out of the first six houses, how many get no mail that day? Out of those that get no mail, how many got no mail because you didn't have any mail to deliver? Try keeping track with a simple picture.

    Once you get the first six figured-out, think about the next six and see what happens.
