Should I join the Club?
At Mr. Vid's Video Rentals you can join his VID Club for a monthly membership fee of $30. Club members pay only $.85 to rent each movie. If you are not a member of the VID club, the movies rent for $2.25 each. What is the least amount of videos would you have to rent each month to make a membership worth the investment?

    Let n be the number of videos you rent. Yu want to find where it's cheaper to join the club. That is,

    30 + .85n <= 2.25n
    30 <= 1.4n
    21.4 <= n

    So, if you rent at least 22 videos per month, it's cheaper to join the club.

    A word of advice: spend more time on your homework, and rent fewer videos!
