Oooh, that's a toughie
I mean, personally, I make my invitations sized proportionally to the amount of guests, but I'm not sure if everyone does.
so it wont be c
No, it is definately c.
how can it be c if it says NOT
Just ask yourself: what is the amount of food, number of party favors, dimension of the intvitations and the cost for 1, 2, 3, ... guests, if its linear then you have proportionality.
Because I was joking ^ Ignore me, I just got a little annoyed because this is an insult to Maths...
BODO I DONT KNOW HOW TO DO THAT
Actually the problem is not well-posed ;-) Ok, so lets start with something simple. If 1 Person eats 1 kg of salat, how much will N persons eat?
? DONT UNDERSTAND
You wonder how much salad you have to buy for the party. All you know is, that every guest will eat 1 kg and you invite N guests. But if that is too abstract, try with 5 guests first.
I THINK IT IS C
Please don't write in all caps, it's like shouting! Do you know that exactly one answer is correct?
So you must think about each option separately. Of course C is one correct answer. But what about a e.g.?
i dont need one
mmh, I don't understand you...
wait what is e.g
i dont need an example though
Oh god... sigh. The answer is obviously c or d. The size of the invitations cannot be proportional to any of the other factors besides the cost of the party. Common sense will let you know that larger/smaller dimensions will cost more or less. This question is an insult to math.
