Question

medal and fan please help me!!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

Samuel has to sell concert tickets worth at least $90. The price of a child ticket is $8, and the price of an adult ticket is $15. Let y be the number of child tickets sold and x be the number of adult tickets sold. Which of the following graphs best models this situation?

Answer 2

idk, i got it wrong before

Answer 3

Please help me @GreenCat @GracieBugg @Nnesha @xapproachesinfinity @kiamousekia @cecormier @Jaseelson

Answer 4

what did you get ??
show ur work plz :)

Answer 5

first translate the words into inequality

Answer 6

what does at least 90 mean?

Answer 7

so do we agree that it would be >=90

Answer 8

x is the number of adult so
the total tickets sold for adult s would be 15x
similarly y # of kids
8y is the total tickets sold to them
so we 15x+8y>=90 yes

Answer 9

ok

Answer 10

now to find the solution for this inequality you will need to draw the line with equation
15x+8y=90

Answer 11

ok so it would be

Answer 12

well you tell me what it would be :)

Answer 13

you know how to sketch a line don't you?

Answer 14

yeah one sec i'm working it out :)

Answer 15

okay:)

Answer 16

I think it would be B

Answer 17

why?

Answer 18

you still have to test a point and where the solution are
if the point we test didn't satisfy the inequality
the solutions must be in the other side of that point

Answer 19

oh ok

Answer 20

don't just guess

Answer 21

work out the solution and be very sure it is the answer :)

Answer 22

you need obviously to draw your solution and forget there options
you draw the line whose equation is 15x+8y=90
test a point
and decide the the solution set

Answer 23

ok

Answer 24

to draw a line you only need to points

Answer 25

yes, ok

Answer 26

wait, will it be greater than?

Answer 27

didn't you pay attention to what i did
i said at least means >=

Answer 28

ok sorry

Answer 29

did you draw the line yet?

Answer 30

the graph should be
http://prntscr.com/6sg9bz
all you need is two points to sketch it why taking too long

Answer 31

now test a point
(0,0) is good

Answer 32

sorry, i'm trying to do 2 questions at once, sorry

Answer 33

keep in mind here we don't not deal with negative part of the xy plane

Answer 34

ok so now I'm just doing this one

Answer 35

ok

Answer 36

as that wouldn't make sense at all in this real life problem

Answer 37

ok

Answer 38

So it's A or B

Answer 39

yes one of them
you decide after testing a point

Answer 40

ok

Answer 41

let me see you work it out :)

Answer 42

don' expect answer all the time, you need to work as well
if you want to learn that is

Answer 43

so have you considered 0,0

Answer 44

yeah

Answer 45

so show the result then

Answer 46

I think it's A because

Answer 47

okay and the reason is
remember math does not believe in i guess either strongly yes or no

Answer 48

ok

Answer 49

Thank you, sorry i wasn't doing a good job doing it with u because i was trying to do another one at the same time

Answer 50

hehe well that is no good my dear :)
you letting me do your work!
you need to focus entirely on understanding one at least before attempting anything else

Answer 51

yeah, it's just I have sooo much work to do today, I guess I'm not going to do it well if I can't focus on it XD

Answer 52

Normally I do it with whoever is helping me

Answer 53

look my point is i will give yu the answer, but what does that do to you
eventually you get stuck with more problem to come and nobody is willing to do others work all the time. So instead learn it yourself here and you will never have any difficulty later :)

Answer 54

If i'm harsh then I'm sorry!

Answer 55

yup, i agree

Answer 56

u aren't harsh!

Answer 57

so back to our story
when i asked you to test a point I'm basically telling pluggin the x and y of that point into our inequality and check if it works
so i said 0,0 is good for our test, in fact any other point would do
15(0)+8(0)=0>=90 we ask is zero greater than 90?

Answer 58

sure it is not!

Answer 59

then the conclusion is the solution are on the other side of the line
including the line itself since we greater than or "equal"

Answer 60

Do you understand!

Answer 61

yes, sorry!!
