Then A or C.
Then the other.

Simply:
B - is found by exp 1 and 2
B increases by 4 rate increase by 4 .... hence B is one order
A - is found by exp 2 and 3
B is double so rate should become 6.4 but it is 4 times lower A is only twice as low .... hence A is two order
C - is found by exp 1 and 4
B increases by 3 so rate should b 2.4 and A falls by half so rate should fall by 4 to 0.6 as rate is already 0.6 .... C is zero
btw you dont need an extra box that is rubbish made up by your teacher , if you dont understand my explanation just ask .Last edited by simon2012; 13-01-2010 at 22:09. -

DID YOU NOT READ THE OP? I ALREADY FOUND OUT B SO I DID DO IT FIRST. I just didn't know how to find A or C. jeez. And I'm not weird, in what way am I weird?
If you want help, ask.

hmm, since your username is mathematics, i suggest you look back to my post on the question(forgot which page it was already). I am not boasting, but really, i find the way i do it with ratios can save you a lot of time in a lot of situation with this type of questions.

When he means an extra box i think he wants to know how to work it out mathematically?
Sorry to hijack this thread but can someone tell me how to work out the orders? I can do it mathematically but that takes too long.
