Question

Hello, please help me with this, I'm really bad at word problems :(

What is the equation using simple equation and one unknown.

a Group of 20 people, adults and children, pay $64 to go to a matinee. The entrance fee for adults is $6 for children $2. How many adults in the group??

Thanks.

Answer 1

\[6(20-y)+2y=64\]

Answer 2

where y is the children then 20-y are the adults

Answer 3

intrepret like this :

\[\large \bf \text{20 people} \rightarrow \text{adults and children }\]

they pay $64

so sum of money paid by adults and children should be $64

for adults charge is $6 and for children $2

Suppose x number of adults were there and y number of children were there

so total cost will be

\[$6 x+$2y=$64\]

we are asked how many adults were there ,and that is x in this equation ,

so solve for x :)

Answer 4

in other meaning\[4x+40=64\]

Answer 5

oh okay. thanks I will study both solutions thanks so much

Answer 6

oh AracindG I cna only use one unknown :(

Answer 7

@levinelevine please do not provide direct answer like that .Instead help the asker get to the solution .refer openstudy COC http://openstudy.com/code-of-conduct

Answer 8

ok haha sorry... sooooo

Answer 9

x is number of adults

Answer 10

that will mean number of adults will depend on only one variable and that is y

Answer 11

got it @miszery ?

Answer 12

I dunno, I think for me since word problems are confusing, I find it best to have the answer and study how it got there. I get confuse trying to solve it otherwise. thanks guys

Answer 13

fisrt you have 2 equations, x+y=20, where x ae the adult and y the children. then you have another equation which is 6x+2y=64. you need to solve for x wich is adults. so first solve for y on the fisrt equation (y=20-x) then input it on the second equation (6x+2(20-x)=64 then simplify and you get 4x+40=64... solve for x and you've got it

Answer 14

okay I unerstand now, so the other unknown is an equation in itself embedded into the second?

Answer 15

if x's and y's cause you truble use whole words like instead of x use adult and instead of y use children. trust me its better that way 'cause when you'll do complicated stuff it will be easier

Answer 16

hey @miszery you can write my x as (20-y)

Answer 17

yesss there are 2 equations and 2 variables

Answer 18

so you will get an equation in y

Answer 19

you can solve for y !

Answer 20

ok yay! thanks guys will work on this on paper now and study it ... it will take a bit LOL xx cheers
