this is one expensive place but how many kids went so we can see how many adults went

That's my problem... It doesn't say... that's the whole question. :/

Set up two equations, one for the total number of people that went, and one for the total cost

oh

ok i will try no promises

@CalebBeavers What do you mean. @ashlynn143 It's okay, anything helps. (:

Call kids x and adults y
so x+y=17 since 17 people went
now try to make one for the cost

How would I make one for the cost if I don't know how many people went?

17 people went

Use the variables...you know the price for each one and the total cost

could this help
y=adult x= child
y(53.50) + x(47.25)

@CalebBeavers ^^^^^

$53.50x + 47.25y = 859.50 ???

Okay, adults can be x. thats right
so now we have a system of equations
x+y=17
53.50x+47.25y=859.50

ok so now what do we do

??? I'm still confused. I'm sorry.. I'm horrible at math and it's been a long day. X(

because we dont know the number of kids

I get what you have so far, but how do we get the number of adults who went?

Solve for y in the first equation

i will try

How.. we don't know what x equals.

Solve for y in terms of x, just isolate y on the left side

okay, so... 47.25y=859.50-53.50x
do I have that right so far or am I doing it wrong?

Solve for it in the first equation
x+y=17
itll be much easier

okay so... y=17+x
... is that right so far?

*17-x

yep, now take 17-x and plug that in for y in the other equation

i got to go sorry

@ashlynn143 it's okay. (:

What do you mean? like: 53.50x+47.25(17-x)=859.50 ???

Yes, now solve for x

How do I solve for x?

Algebra...just solve like normal theres only one variable now

yeah, but it's 17-x ... gah!! I'm confused. :(

Do you know how to solve an equation?

Distribute the 47.25 into the parentheses first

oh... okay, so... 53.50x + 803.25 + x = 859.50
??? right? What next? (:

You didnt multiply the x..
53.50x+803.25-47.25x=859.50

ohh... okay. duh. Alright. so 53.50x + 803.25 - 47.25x = 859.50.. now what?

combine like terms and subtract 803.25 from both sides

okay... so I get 57.

Now what?

thats not right

What? :(
53.50x + 503.25 = 859.50
6.25x + 503.25= 859.50
-503.25
6.25= 356.25
+6.25
= 57

6.25x=56.25
x=56.25/6.25

9? ?

(: YOU ARE AMAZING!! THANKS SO MUCH!!!! :D
