There are an infinite number of possibilities, but the ratio students of the second class is 2.14285714286 times the number of students in the first class.

Here is how I set up the equation to solve the problem:  0.7X + 0.92Y = 0.85(X + Y)

X = the number of students in the first class
Y = the number of students in the second class

how you going to solve that equation dan?   you've only got 1 equation with 2 unknowns.

You can combine like values to come up with a ratio between the two numbers.  That's why I said there are an infinite number of possibilities, but the ratio is fixed.  The second class has 2.14 times the number of students of the first class.

But you are right, we cannot know how many students are in either class until we know how many students are in one of the classes.

I saw the answer and it is completely screwy to me.

I see why no one gets it.

Since it is a multiple choice question, MAYBE someone can guess it.

dan's ratio is right.  the answer is infinite, but it has to be in multiples of 30 students in the democratic class, and 14 students in the republican class, in order to have whole numbers of students. 

I got it.  There is no single finite answer.  The answer is a ratio - 2.14

the ratio is right but you did not solve the problem.  you did not say how many students were in the democratic (92% average grade) or the republican class (70% average grade).  the fact you think just getting the ratio correctly is answering the question is kinda weird.  go back and read the question....

If the LCD is 30, then the answer is 3,000 democrats and 6,420 Republicans.


Yes I did.  There are an infinite number of possibilities.  That is the answer.  I could provide several examples, each of which meet the criteria.


Because there is no single answer that meets the criteria.


Nope.  The first thing I said was there are an infinite number of answers.  The common factor among all the answers is the ratio 2.14.


Go back and read my answer where I said there are an infinite number of answers.  You must have missed that part.

0.07Y = 0.15X

you did not name any answer, dumbass.  just giving the correct ratio that every correct answer has is not the ANSWER to the question- how many students in each class?  have you ever taken any English classes?

YOU WERE NOT ASKED TO GIVE THE CORRECT RATIO OF THE TWO CLASSES. 

LOL!  I named an infinite number of answers.  You even admitted there was not just one answer.

Dumbass.


... allows you name any class size you want.


I told you already.  There are an infinite number of examples.  Do you want me to pick just one?  OK - 3000/6420.


Do you?  Why can't you read simple English?  And why don't you know how to capitalize?


So?  I was just being helpful.

you didn't name any, liar.  are you serious?

wrong again, illiterate one!!  plug in any size class for any one of the two classes, and if it is not 14 or 30 or a multiple of 14 and 30, you will not get a whole number, and classes cannot have fractions of students, dumbass.  you got half of it right, and that was pretty good.  just not good enough. it was not the answer or an answer.  it was a ratio.  I will be lenient and give you a solid B-. 

and the answer you gave is not correct.  real close, but not correct.  it does not give a whole number. 

wrong!! wrong!! wrong!!  you have to give the higher grade class a class size a multiple of 30 and the smaller class size a multiple of 14 or you will not get exactly 85% as the average of both classes....due to the fact the ratio is infinite and will always be a tiny bit off if used any other way. 

Liar.  I did name one.  I also said there were an infinite number of answers.

Because ypu don't want to be educated in math?


Liar.

Nope.  I am absolutely right.  You are an idiot and a liar.


Nope.  I got it 200% right.


Idiot, I told you there were an infinite number of answers.


Wrong.  The answer I gave is absolutely correct.  You can't read, can you, idiot?

Right right right!


I did.  There are an infinite number of multiples of 30.  Infinite is the answer.  Learn how to read, idiot.

quit lying, bitch.  the answer you finally gave, after giving no answer at all for a few posts, is wrong, stupid ass.  because if you take 6420 as the class size of the 92% democratic class and 3000 as the class size of the 70% republican class, and do the math, as so:

6420 x 92 = 590640 and 3000 x 70 = 210000,  and take that result, 800640, and divide that result by the number of students in both classes combined, 9420, you do not get an exact result, as the problem said- 85% - not "approximately 85% - as your wrong answer comes up with- 84.9936305732...%- not 85%. close but no cigar, dumbass. 

I never started, bitch.


Nope.  It is absolutely right.  Try it if you don't believe me.


OK, you get a result of 84.99%


LOL!

the fact you think two different numbers are the same proves how ignorant you are of math.  get a clue.  close counts in horseshoes and hand grenades.  you were asked for an answer of the class sizes combined of 85%, not "approximately 85%".

LOL!


... math.


LOL!  It rounds off to 85%, idiot!

if you had used a multiple of 30 as the class size for the democratic class, and 14 for the republican class, you would get THE RIGHT ANSWER...WHAT YOU GAVE IS WHAT SCIENTISTS CALL "THE WRONG ANSWER."  it was not 85%.  a miss is as good as a mile.  get it, dummy? i guess in Alaska they give points for being close. 

If Food Stamps are given out at $200 per month along with Section 8 housing and a Welfare Check of $300 each month,
    and a Bro' buys $60 of crack/meth/pot every day and $20 of booze, then what day of the month will AssHat-LaPuta
    have to go out in the ghetto and sell himself on the "down-low" to support his drug habit?

Any guesses?

Why would I do that?  Democrats are clearly less intelligent than Republicans.


I did get the right answer.  There are an infinite number of combinations.


Nope.  I gave what scientists call the "definitive answer."


Yeah it was.


Nope.  84.99 is no different than 85 on your GPA.

Get it, dummy? I guess in Texas they give points for being stupid.

what passes for trump logic- 84.99 is no different than 85 on your GPA.  one more time.  if 84.99 was as close as you could ever get for an answer, not 85 on the button, you would have a point.  But it is not.  Using multiples of 30 as the democratic class average (92%) and similar multiples of 14 as the republican class average (70%), you will get a combined class average of exactly 85%.  Close your book, put down your pencil.  Test over. 

Unbelievable that oscar chooses to argue something so ridiculous.

I mean really?  Dan seems to have taken all points into consideration and given a very sound answer.

Were this true "new math", he would have told a wonderful story without once mentioning a number.

Nope.  I can get there exactly with any number of infinite answers.


Yep.  85 on the button.


LOL!  Yep, there are an infinite number of answers even using that additional criterion.


Yep.  That is one answer.


Yep.  Now sit down and shut up.

shut up, fool.  i asked for the number of students in each class, jackass, not what ratio could be used...get it, stupid?  and when he did provide an answer, it WAS FUCKING WRONG...get it, stupid?  the numbers he gave for each class did not create an average score of 85%.....it created an average score very close to that, but not that.  you apparently are too stupid to understand math.  we not want approximate numbers unless the question asks for them.  there were class numbers that could be used THAT WOULD CREATE AN EXACT CLASS AVERAGE OF 85%, BUT DUMBASS DID NOT GIVE THOSE ANSWERS, get it, stupid?  you don't know shit about anything, especially numbers, so shut the fuck up. 

That doesn't sound like you are shutting up, hoosier.  Sit down and shut up.

come back when you can answer a simple math problem, bitch.  until then, if i want any shit out of you, I will squeeze it out the top of your head. 

I did answer correctly, diaper loser hoosier.  Now sit down and shut up!
