Answer 1

Be sure of 1 and 2 100% now.
They are correct, and you got the idea!

Answer 2

but, what's #3?

Answer 3

I'm so confused .-.

Answer 4

and hey 3mar.

Answer 5

And also you can model and formulate what you understand well, while others can't.

Answer 6

No for what you are stuck in:

Answer 7

Thank you for the medal!

Answer 8

could you explain why it's no?

Answer 9

i need a 2/3 sentence explanation.

Answer 10

Ok

Answer 11

wait

Answer 12

it can't be no

Answer 13

it's not a yes/no question

Answer 14

One of two:
1. the question is wrong about chairs, and it shold be tables.
2. It is correct and he just want you to express that it can't be and does not make sense.

What you think?

Answer 15

Do you still need help with #3 @JamalJunior?

Answer 16

Yes

Answer 17

i dont think the question is wrong @3mar and i also dont think my teacher wants me to express anything here

Answer 18

Alright. It looks as if you know how to read the graph because I looked at #'s 1 and 2 and they look very good. So, do you have any ideas on how many tables they could build?

Answer 19

It is just one possibility!
So what you think brain?

Answer 20

There are actually 3 different values for question 3.

Answer 21

Yes I have

Answer 22

@JamalJunior Do you have any educated guesses for the answer to question 3?

Answer 23

@JamalJunior

Answer 24

max. number of tables 21 with min number of chairs 2
or
15 tables with max. number of chairs 5
or
least number of tables 9 with 3 chairs

So what is the relation between these values and 15 chairs?

Answer 25

Can you discuss that with me, brain?

Answer 26

Are you talking to me? @3mar

Answer 27

Yes.

Answer 28

Then what?

Answer 29

This isn't my question, and I don't think it is yours. Why are you asking me questions?

Answer 30

to know!
do you mind? or you don't know?

Answer 31

Well, I know the answer to JamalJunior's question. As for yours, you mistyped the information.

max. number of tables 21 with min number of chairs 2
or
15 tables with max. number of chairs 5
or
least number of tables 9 with 3 chairs

So what is the relation between these values and 15 chairs?

The x value represents the chairs, and the y value represents the tables. So, if they built 21 chairs, then they could only build 2 tables. Also, none of this is relevant to his question. His question asks how many tables could be possibly built if the company had 15 chairs. There are 3 different possibilities which can be easily read from the graph. So, is there anything else you want to know from me?

Answer 32

The shaded region, or feasible region, is all possibilities. So, to find the answer to his question we just need to follow the chairs up to 15 (x value) and then look at which y values are in the shaded region with the x values.

Answer 33

You know? just this make a difference: "The x value represents the chairs"
So let me thank you firstly.
But actually, there are 4 possible number of tables, not only 3. am I right?

Answer 34

I'm so confused .-,

Answer 35

could someone tell me the answer .-.

Answer 36

it seems like everyone is confused

Answer 37

Easy Jamal. Brain clarified it well.

Answer 38

So is it 3 tables or 4

Answer 39

Take that, It will show you.

Answer 40

You have 4 different options that 3mar shows you in the picture. It is 2,3,4, and 5

Answer 41

I really appreciate your illustration, @BrainDead!

Answer 42

You did the illustration, I did more of an explanation.

Answer 43

The most important thing that @JamalJunior got the idea ;)
Did you JamalJunior?

Answer 44

5 Tables, 15 chairs, yes?

Answer 45

5 is not the only answer. The question has 4 different answer choices. Hence why the question asks you for ALL possible answers.

Answer 46

Ohhh. I see

Answer 47

What should I write as my explaination

Answer 48

What BrainDead has explained:

The shaded region, or feasible region, is all possibilities. So, to find the answer to his question we just need to follow the chairs up to 15 (x value) and then look at which y values are in the shaded region with the x values. The question has 4 different answer choices. Hence why the question asks you for ALL possible answers. You have 4 different options shown in the picture. These are 2,3,4, and 5.

Answer 49

@jamaljunior
Glad that you got the help you needed from @3mar and @braindead. Congrats.

Perhaps it was not explained to you, but there is a very important observation you need to make:
- When a boundary of the shaded region is a SOLID line (as is the case here), any point falling on the boundary line is IN the feasible region.
- When a boundary of the shaded region is a DOTTED line, any pint falling on the boundary line is OUTSIDE of the feasible region.
- When a point falls on the intersection of a DOTTED and a SOLID line, the point is OUTSIDE of the feasible region.

Also, as @3mar was wondering also, I do not understand why or how you got the first two questions answered perfectly, as if you understood the concept, but get stumped with #3.
