Question

HELP. ME....

A primary school is planning to hold a fete, but needs help on figuring out how much to charge for entry. they intend to have an "all you can eat" sausage sizzle, but they think each adult will east about $3 worth of sausages, and each child $2 worth. The cleaning after the event will be $300.They want the parent ticket to cost twice as much as the child's ticket, and they expect that, 1.7 parents and 2.3 children will come from each family. how much will they need to charge for adults and children if they are expecting 120 families to attend and dont want to make any loss/profit?

Answer 1

I know the answers but i don't know how to solve it

Answer 2

"The of cleaning after the event will be $300." Typo??

Answer 3

oops

Answer 4

And does the problem actually says fractions of people? 1.7 parents and 2.3 children?

And can you tell me the answer so I can see if I did it correctly and then explain to u if I get it right?

Answer 5

yes it does says fractions. I rather not tell the answers though, i want to know if you know what youre doing

Answer 6

He already did the work

Answer 7

Ok. Hold up. I'm gonna try to solve it then..

Answer 8

sinkin math, you adult ticket have to cost as twice as the child's ticket.

Answer 9

lol ok

Answer 10

This is so weird
Got $0.17 for child and $0.34 for adult

Answer 11

erm thats wrong

Answer 12

im using my sister's account. she says it wrong but she wont tell me WHYYYYYY

Answer 13

:(

Answer 14

I'm thinking about systems, but the "don't want to make any loss/profit?" doesn't add up for me.

Answer 15

Would it be referring to breaking even?

Answer 16

well, since they are gonna have cleaning, its -$300, and the sassuages.

Answer 17

Answer 19

"perhaps we multiply 120 and the amount of parents and children then multiple the total to the supposed consumption of sassuages." -Sis

Answer 20

Did your sister come up with this problem?

Answer 21

i think shes speaking in another language. help me break it down on me?

Answer 22

$2.14 for child and $4.28 for adult???

Answer 23

"Exactly"-sis

Answer 24

can you know tell me the solution

Answer 25

@tHe_FiZiCx99 dosent matter if she did or didnt.

Answer 26

Just a thought, whether she included enough information. Looping ~

Answer 27

YAY!

So I multiplied by 120 to the expected number of parents and children that were expected to show per family
And got 204 adults and 276 children

Answer 28

yeah i also did that. i then multiplied the sassuages

Answer 29

Yea ^ and add the cleaning so that's a total of $1464

Answer 30

ok that when the question lost me

Answer 31

oh wait you DIVIDE

Answer 32

Let
a= price of adult ticket
c= price of children ticket

204a+276c=1464
And
a=2c

Use substitution and solve for c

Answer 33

you lost me at "let"

Answer 34

They're just variables

Answer 35

jk actually you lost me at a=2c

Answer 36

how did that happen

Answer 37

how are there 2c's??

Answer 38

a=2c
I translated the sentence that adult tickets are twice the price of children

Answer 39

oh damn im dumb

Answer 40

so um now what

Answer 41

Substitution to solve for c

Substitute the second equation into the first
204(2c) +276c=1464

Answer 42

then

Answer 43

can oyu finish it

Answer 44

The rest is just algebraic

684c=1464
Divide both sides by 684
And round to 2.14
So c=2.14

Plug this into second equation
a=2(2.14)
a=4.28
