Answer 1

Oooh, that's a toughie

Answer 2

i know

Answer 3

I mean, personally, I make my invitations sized proportionally to the amount of guests, but I'm not sure if everyone does.

Answer 4

so it wont be c

Answer 5

No, it is definately c.

Answer 6

how can it be c if it says NOT

Answer 7

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.

Answer 8

Because I was joking ^ Ignore me, I just got a little annoyed because this is an insult to Maths...

Answer 9

OHH

Answer 10

BODO I DONT KNOW HOW TO DO THAT

Answer 11

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?

Answer 12

? DONT UNDERSTAND

Answer 13

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.

Answer 14

I THINK IT IS C

Answer 15

Please don't write in all caps, it's like shouting!

Do you know that exactly one answer is correct?

Answer 16

no

Answer 17

So you must think about each option separately. Of course C is one correct answer. But what about a e.g.?

Answer 18

i dont need one

Answer 19

mmh, I don't understand you...

Answer 20

wait what is e.g

Answer 21

for example

Answer 22

i dont need an example though

Answer 23

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.
