Question

Castel and gabriella are selling pies for a school fundraiser.Customers can buy apple pies and lemon meringue pies.Castel sold 6 apple pies and 4 lemon neringue pies.Gabriella sold 6 apple pies and 5 lemon meringue pies.What is the total cost for each of one apple pie and one lemon meringue pies can someone help me solving this by using the elimination method?

Answer 1

so ok you mean like...
6a+4a=x
6a+5l=x
?

Answer 2

and then elimination method? to that system of equations?

Answer 3

ok looking at this though is there a total cost to how much EACH person made? this problem looks incomplete

Answer 4

yes do you know how to solve it......HOW?

Answer 5

I do this problem looks incomplete.

Answer 6

like how can we find the total cost of each product when we don't know how much they made?

Answer 7

Is there more to the problem you forgot to add on?

Answer 8

No ....... you have to find the total cost did you read the problem cuz the numbers are there

Answer 9

Castel sold 6 apple pies and 4 lemon neringue pies.Gabriella sold 6 apple pies and 5 lemon meringue pies

Answer 10

those are the only numbers you provided tho.

Answer 11

yes r u a freshman

Answer 12

no i just don't understand how you would find one apple pie and one lemon meringue pies if you don't know what the total outcome is

Answer 13

like apple pie and lemon pie = total product
but we dont have total product to work from. we just have two variables on the side when we set the problem up

Answer 14

you have to create a system of equations to figure out the problem

Answer 15

right but what does each one equal to?
6a+4a=x
6a+5l=x

Answer 16

6a+4l=x
6a+5l=x

Answer 17

you can't solve this without having the total cost spent

Answer 18

yes kellie that's what i'm saying.

Answer 19

@kelliegirl33

Answer 20

unless the two total products are supposed to be set equal to each other?

Answer 21

like:
6a+4a=6a+5l?

Answer 22

i'm trying to tell y'all that you solve by eliminating the equations

Answer 23

you can't use eliminating the equations without a total product from each equation
http://www.mathportal.org/algebra/solving-system-of-linear-equations/elimination-method.php

Answer 24

you cannot eliminate

Answer 25

Is there more to this problem ?

Answer 26

no

Answer 27

i'm sorry i really do want to help but you cant solve that problem unless you know the total spent for each person.

Answer 28

you cannot find the cost of one product if you do not have any money value in the problem, such as the total cost

Answer 29

um i did leave out 1 part i'm SO SORRY

Answer 30

IT'S OK just give it to us so that we can help you

Answer 31

CASTEL'S TOTAL COST IS 80 DOLLARS and GABRIELLA'S TOTAL COST IS 94 DOLLARS I'M SORRY I'M TIRED

Answer 32

jessie....I am not gonna take over this problem....so..um...you got this ?

Answer 33

yes i do :)

Answer 34

it's ok tionne i'll walk you through it

Answer 35

OK

Answer 36

do you need help ?

Answer 37

6a+4l=80
6a+5l=94

Answer 38

ok first
-(6a+4a=80)
6a+5l=94

6a+5l=94
-6a-4l=-80

Answer 39

so you add

Answer 40

& y is it negative

Answer 41

you need to reverse the equation so that the variable can cancel out.
then you can find l.
after finding l you can input that number into the original equation to find the value of a.

Answer 42

6a + 4l = 80
6a + 5l = 94 --->(-1)
-----------
6a + 4l = 80
-6a - 5l = -94 (result of multiplying by -1)
------------add
-l = -14
l = 14

Answer 43

yeee and now you just have to add 14 for l into the original equation so that you can find a!

Answer 44

so you add 4 +14 and 5 + 14 right

Answer 45

uhm ok i mean sub 14 for l in any of the equations

Answer 46

like 6a + 4(14)=80

Answer 47

that will help you find a

Answer 48

you multiply

Answer 49

yes multiply
6a+4(14)=80
6a+56=80
6a=24
a=4

Answer 50

after you got that doesn't it have to be a order pair

Answer 51

nicely done jessie

Answer 52

thank you @kelliegirl33
and tionne it can be but they only asked for for total cost of each one, so i mean
4$ per apple pie
and 14$ per lemon pie should be an adequate enough answer

Answer 53

@kelliegirl33 opinion on that?^

Answer 54

she left but thanks jessie um if you don't mind if you have time to help me with one more please?

Answer 55

I will most definitely take a look

Answer 56

ok so The school that imani goes to is selling tickets for a annual dance competition.On the first day of the ticket sales the school sold 3 senior tickets for a total of 69 dollars.The school took in 91 dollars on the second day by selling 3 senior tickets and 3 child tickets. What is the price of one senior ticket and one child ticket and its using the elimination again

Answer 57

it does not have to be an ordered pair....just post your answer like jessie did above :)

Answer 58

3s = 69 (solve for s and get the cost of a senior ticket.

3s + 3c = 91 (sub in what you got for s in the above equation and then solve for c.

Answer 59

3s=69
3s+3c=91

find s first: 69/3=23

plug it into the second equation and find c
3(23)+3c=91
69+3c=91
3c=22
c=22/3=7.33

Answer 60

o god

Answer 61

do you need anymore help?

Answer 62

hold on god

Answer 63

why did you divide

Answer 64

what you do to one side you must do to the other. i will go step by step. sorry i did geo last year and i could leave out things like subtracting and stuff. i just had to imply that i did it.
3(23)+3c=91
69+3c=91
-69 -69
3c=22
3c/3=22/3
c=22/3
c=7.33

was that clearer?

Answer 65

yes bless me

Answer 66

hahaha i'm glad you understand. math takes a lot of observing. is that all though?

Answer 67

yes thanks jessie your name reminds me of the show but that's it thank you & have a goodnight :)

Answer 68

hahaha i get that a lot and you're welcome have a great night as well!
