Can someone please remind me of the question about the lollies and choc ices?

I fear I messed this up :mad:

You had to make them into simultaneous equations, work out one and then substitute your answer to find out the other price.

What was the answer?

50p, i think.

yeah i did this. i got the answer to being 50p

What were the prices?

One had 2 lollies 3 chocs
The other had 2 lollies 5 chocs.

Also how many marks were for this and can you remember how many marks there were for the simultaneous equations?

They didn't tell you it had to solve it via a simultaneous equation.. my friend got 50p and she did some other weird way!

If you get the correct answer, even with crazy workings-out, you get all the marks... i think they only take the workings into consideration when you get the answer wrong and they want to check to method.

They did tell you the prices they bought them for...

It was something like 2 lollies 3 choc ices for £4.20 and 2 lollies 5 choc ices for £6.40 or something like that.

(and I meant how many marks were there for the simultaneous equations on another question ... it was 4 or something near wasn't it?)

Probably was around 4 marks... most were 2/3/4, occasionally 5 marks.

I think it was 3 or 4 marks. I recognised it as a simultaneous equation straight away luckily, and used the normal method to find 50p. Some people used trial and error; just looking at the values and putting in something that could work. These people also got 50p. The other simultaneous equation question was 2.5 and -1 I think.

labtec 2.5 is right i think but i kept mine in fraction form, 10/4 is that still correct

So can anyone on edexcel A (the linear) confirm that there was no question on similtaneous equations with y=5x^2 and y=3-14x because i think they appeared on the Edexcel B paper so i just panicked a little when i saw people on another thread talking about it
