    Now for this challenge you're going to be answering some story problems, they range from fifth grade material to high school. Your job is to answer these questions. The first person to successfully answer all questions or the one who has answered the most will win head of household. Now those answers have to be correct so just submitting me something doesn't mean your all up for eviction.

    READY?
