Question

Answer 1

Well the total liters they need is 100000

Each trailer can carry 2400 + 2200 = 4600 liters

So how many trailers would it take?

\[\large \frac{100000}{4600} = ?\]

Answer 2

that should be around 22

Answer 3

i was thinking it would be 2400x + 2200y = 100000

Answer 4

and then have the inequality of x >= y >= 0

Answer 5

(to fulfill the contract)

Answer 6

It would be like that if the trailers could run by themselves, but they're just attached to the tankers...so they just fall in with them

Answer 7

But as far as I see.....22 is correct :)

Answer 8

oh :/

Answer 9

I don't think it is, it's supposed to be a greatest common divisor question

Answer 10

Aww why the face :(

hmm, lets see...maybe I'm missing something here

Answer 11

Haha sorry, but there's no way it can be that easy

Answer 12

No I agree if its not just a simple algebra problem lol...trying to see what I'm missing :P

Answer 13

I did come up with a solution though, don't know if it's right though

Answer 14

Actually, what did you come up with?

Answer 15

well basically there are 4 possible solutions for the equation 12x + 11y = 500

Answer 16

(divided by 200)

Answer 17

we have (5,40), (16,28), (27,16) and (38,4)

Answer 18

However, only two of them fall into the inequality condition (which is x >= y >= 0)

Answer 19

which are the last two...

Answer 20

and since x is the number of tanker and y is the number of trailers... we choose the lower x

Answer 21

which is 27.........

Answer 22

SoOoOo yeah.

Answer 23

that's what i'm thinking, hope that makes sense

Answer 24

Nope that is absolutely correct!! haha sorry for thinking it was simpler than it was, haven't worked with euclidean in a while!

Answer 25

are you serious??

Answer 26

Yes!! and your reasoning is perfect as well, exactly the train of thought you needed to have here

Answer 27

oh my gawdddddd..... I need a nap. I've been thinking this was wrong for so long!!

Answer 28

Thanks for helping though! <3

Answer 29

Lol NO!!!! dont second *or like 100x over* guess yourself lol

That's what I was doing on my fluid mechanics for the past hour XD

Good job <3

Answer 30

B) Thanks!
