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

@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?

CalebBeaversBest ResponseYou've already chosen the best response.2
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)

$53.50x + 47.25y = 859.50 ???
 one year ago

CalebBeaversBest ResponseYou've already chosen the best response.2
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

AGummiBear55Best ResponseYou've already chosen the best response.0
How.. we don't know what x equals.

CalebBeaversBest ResponseYou've already chosen the best response.2
Solve for y in terms of x, just isolate y on the left side
 one year ago

AGummiBear55Best ResponseYou've already chosen the best response.0
okay, so... 47.25y=859.5053.50x do I have that right so far or am I doing it wrong?
 one year ago

CalebBeaversBest ResponseYou've already chosen the best response.2
Solve for it in the first equation x+y=17 itll be much easier
 one year ago

AGummiBear55Best ResponseYou've already chosen the best response.0
okay so... y=17+x ... is that right so far?
 one year ago

CalebBeaversBest ResponseYou've already chosen the best response.2
yep, now take 17x and plug that in for y in the other equation

@ashlynn143 it's okay. (:

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

CalebBeaversBest ResponseYou've already chosen the best response.2
Yes, now solve for x

How do I solve for x?

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

AGummiBear55Best ResponseYou've already chosen the best response.0
yeah, but it's 17x ... gah!! I'm confused. :(

Do you know how to solve an equation?
 one year ago

AGummiBear55Best ResponseYou've already chosen the best response.0
Yeah, but it's just confusing because there are no real numbers... like 17x throws me off and gets me all confused.
 one year ago

AGummiBear55Best ResponseYou've already chosen the best response.0
Like if I were to solve for x, I'd have to isolate the x, but I don't know how in the world to do that because the 17x is throwing me off and I'm confused on the whole problem now. :( :(

CalebBeaversBest ResponseYou've already chosen the best response.2
Distribute the 47.25 into the parentheses first
 one year ago

AGummiBear55Best ResponseYou've already chosen the best response.0
oh... okay, so... 53.50x + 803.25 + x = 859.50 ??? right? What next? (:
 one year ago

CalebBeaversBest ResponseYou've already chosen the best response.2
You didnt multiply the x.. 53.50x+803.2547.25x=859.50
 one year ago

AGummiBear55Best ResponseYou've already chosen the best response.0
ohh... okay. duh. Alright. so 53.50x + 803.25  47.25x = 859.50.. now what?
 one year ago

CalebBeaversBest ResponseYou've already chosen the best response.2
combine like terms and subtract 803.25 from both sides
 one year ago

AGummiBear55Best ResponseYou've already chosen the best response.0
okay... so I get 57.
 one year ago

AGummiBear55Best ResponseYou've already chosen the best response.0
What? :( 53.50x + 503.25 = 859.50 6.25x + 503.25= 859.50 503.25 6.25= 356.25 +6.25 = 57
 one year ago

CalebBeaversBest ResponseYou've already chosen the best response.2
6.25x=56.25 x=56.25/6.25
