Maybe you had better concentrate on paper 2 and heed the guides that are flying around OK

the question on the lone on which she should choose half the people in my class got the first while the other half got the second at first I thought the second but then I said the first choice would be better

It was the second one. Difference wasn't much between them, about 100euro or so.

Ya it's 75.5% markup. It asks you the Markup, or % profit markup, of the whole transaction. % Profit Markup is (Profit / Cost price) x 100.

The cost for her to buy 25 Blazers and 25 Trousers is €1250.

She sells 25 sets:

22 @ €89.95 each.
3 @ €89.95 - 20% discount = 3 @ €71.96.

(22 x €89.95) + (3 x €71.96) = €1978.90 + €215.88 = €2194.78 (Total sales from 25 sets of Blazers/Trousers)

Profit = €2194.78 - €1250 = €944.78. (Total sales minus what it cost her to buy the stock)
As you can see the Profit is almost the same as the cost to buy it. So % Profit should be high.

% Profit = (€944.78 / €1250) x 100 = €75.56%.

I did 2194.78/1250 x 100 to get 75.58.
Probably will give the marks for either way seeing as the difference is minimal.

That's how I did it too. I must say I'm pretty chuffed

Just wondering how people got on with question 8 d the value of h that gives the max volume of the box
did you do it by algebra or differentiation

Used differentiation and let it =0 and got the possible values 2 and 6. Someone pointed out that you could just look at the diagram to tell it wasn't 6 which is true but I didn't think of that at the time. Instead I subbed both values into the volume formula and got 0 for 6 which of course is wrong and 128cm3 for 2 which must've been the max value.

I derived the volume formula once, then simplified it by dividing everything by 12. Then it was a simple quadratic equation so I got x = 6 and x = 2.

Then to find which was the Max and Min I got the second derivative of the volume formula and subbed in 6 and 2, this gave me 2 to be the Max.

I was doing it up until today and dropped. Didn't feel like I'd pass it, so didn't risk it.

I was the exact same only I knew I wouldn't pass it! Not worth the risk really unless you'd be willing to repeat if it went belly up.

Just realised I forgot to write in my calculator information on the front of the paper, is that important?!

Yuuus.. Got that bang on. However, I must say that the paper was harder than I expected it to be. By my very rough calculations I got 75% on paper 1 alone.. hoping to bring that up a bit with paper 2.

The questions on the very last page were a bit messed up..

Was her percentage markup definitely over 70%

Me too! I was so confused what level paper I should take that I panicked I just wrote my exam number and didn't look anywhere else. Is it a very serious matter?

what graph did people pick for Q4 (is was pick graph A,B,C or D for quadratic funcations)

Also for Q9 what graph did ye draw..it was the rocket question.. I just plotted points and then joined them

get over paper 1 it's done...focus on paper 2 people!!

Saxo

Anyone know what'll come up in paper 2?? haven't a clue what to study for it

Write it on Paper Two and say you used the same calculator in Paper One.

i guessed d anybody know the correct answer?

I think it was D. When you differentiated the function and worked out X in the slope function it equalled .5, and the graph had a turning point at x=.5
