At Mr. Vid's Rentals you can join his VID 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. How many vidoes would you have to rent each month to make a membership with the investiment?

Please help me...I need a formula
