At Mr.Vid's Video Rentals you can join his VId Club for a monthly membership fee pf $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 videos would you have to rent each month to make a membership worth the investment?

costmembers=30+.85N

costnonmembers=2.25N
set the costs equal, and solve for N

I don't understand your answer, please explain more.

30+.85n=2.25n

I'm sure you know how to solve equations..

hey....i don't understand the question either....ii have two formulas too

What are your formulas?

Hmm that sounds right , But mr hs said that the equation was y=30 * 2.25x , So i don't know , This is confusing :/

lol...i agree 2...but if y=30*2.25x ....we know what x is but then what is y....877.5 have to do with anything...i did 2.25*13*30=877.5..

Hmm, well yesterday when i was on here someone told me that the answer was -

$30 / $.85 = 35.3 or 36 videos. and i think that's right.. But idk . didn't he say we needed a chart ?

yeah....idk...yeah my mom was helping me 2 and she got this.....but then i went on 2 this and someone told me 30=2.25x.....well that's not the problme..the thing is what is the chart

I know right. Um who do you know that would know the chart ?
