So that means company B sells it for a $1 per cubic foot, right?

- anonymous

i think com b will save more...because of cubic yards
but idk how much u will save

- anonymous

right

- anonymous

it will take more for com a..just to get cubic yrds

- brinazarski

Well... if there are three feet in a yard, you'd multiply the cost of company A by 3, correct?

- anonymous

tht would give me 9

- anonymous

nvm i lookd at the wrong one

- brinazarski

So what would you get, then?

- anonymous

33

- brinazarski

Okay, so that's in terms of cents. Also, the answers are in terms of cents, so you'll want to convert company B to cents. So, company A is 33 cents per yard, while company B is 300 cents. Do you know what to do from there?

- anonymous

No. im completely clueless.. i know it may be easy but math isnt my best buddy

- anonymous

im struggling and if i dont complete this id hv to retake the class.

- anonymous

its a whole bunch of mathical problems i must do..this is only the half of it

- brinazarski

I know, same here here >< I just happen to get this question. Well, what do you think you should do?

- anonymous

umm...
let me think

- brinazarski

The more you think about how to do it, the more you'll memorize and it can become easier

- brinazarski

Take your time :)

- anonymous

i have bad mem :\

- anonymous

well not rlly tht bad but..its hard to rem some stuff like math probs i did yesterday.

- brinazarski

With practice, it'll become better. Latin is my best subject, but I used to have to study A LOT for it. When I didn't study in my Freshman year, I got like 75s, maybe 80s if I was lucky. I got into the habit of studying, which improved my memory a lot. This year, Junior year, I don't even study anymore and I get around a 99 on everything. It just became second nature to me. Other topics, however... not as easy :P

- brinazarski

For this question, you might be overthinking it. Don't stress, try thinking about it logically :)

- anonymous

Sorry my tech was talkn 2 me

- anonymous

your right

- brinazarski

It's okay :)

- anonymous

lol i added sub multpied and divided 30 and 300

- anonymous

multiplied

- anonymous

got nothing

- brinazarski

Hmm... apparently, from Googling, a cubic yard is 27 cubic feet. I'm trying to solve it and not getting anything, so that's probably why. The math has to be reworked a bit, then. It's 300 cents for 27 cubic feet, and 11 cents for one cubic foot. If you wanted 27 cubic feet, or a yard, from company A, it would be 297 cents. The reason being, is that... let me draw it out, unless you understand why it's 297 cents?

- anonymous

u may draw it out

- brinazarski

I think the reason a cubic yard is 27 feet is because it's cubic... yes, there are three feet in a yard, but you have to cube that. So, 3^3 = 27.

- anonymous

oh ok

- anonymous

i may have to go in a few but ill try to get back on in my nxt class

- anonymous

idk if id still hv the same question when i log back on to my thing

- brinazarski

|dw:1336153659054:dw|

- anonymous

it may change. nice example drawing

- brinazarski

Alright then, how many mins you have left? And thanks!

- anonymous

uplike maybe 9

- anonymous

um*

- anonymous

cross multiply?

- brinazarski

For now, the answer is Company A, save 60 cents, since you might not have this question. And yes, cross multiply :)

- anonymous

seems easier when i look at it tht way :\

- brinazarski

I can try explaining while you're still here, if you want!

- anonymous

Thanks for your help.

- anonymous

sure

- anonymous

i have like 8 or 7 more probs just like it..so id need the help

- anonymous

and i cnt get anymore wrong or it wont count as completed

- brinazarski

Find me at your next class for the problems?

- anonymous

Sure.

- anonymous

my next class is art :3

- anonymous

it has a computer in there so..id try to get on.

- brinazarski

And you're welcome! So, we figured out that company A sold 27 cubic feet, or a cubic yard, for 297 cents. Meanwhile, company B sold the same amount for 300 cents. So, you multiply them by 20, since you want 20 yards of gravel. Then you subtract the answers. So, 20(300) - 20(297) = 60. That's all! Understand?

- brinazarski

A fellow art major :)

- anonymous

Yes i get it.

- anonymous

cool :)

- anonymous

but just in case i may still ask u to guide me.

- brinazarski

Like I might've mentioned earlier, I generally suck at math, so I can't guarantee I'll get you the right answer for your next questions >_<;; It's your choice. And okay! I'll be on for a bit

- anonymous

Oh thank you anyway for at least tryn. :D

- brinazarski

You're welcome :)

- anonymous

oooh i got 2 mins left!

- anonymous

1min

- brinazarski

Hmm, so if you get back on, are you just going to message me or something? And how long should I wait before getting off?

- anonymous

not long my art class isnt far

- brinazarski

I came on here because I have an SAT II Math level I test tomorrow...I actually took the day off to study ><;;

- anonymous

unless my teacher says i cant get on

- anonymous

bye. takes me like 3 mins to get there. or 4

- brinazarski

So, about 20 mins, let's say?

- brinazarski

Ah, you left >< After 20 mins, I 'll just assume your teacher said no. If they say yes before that time, I'll be here
