    Question 15 did not equal to £7766.22
    Because 1st year depreciated by 23%
    so 0.77 x 15000 = £11550
    then after the 1st year it was 18%
    so 0.82 x 11550 = £9471
    therefore no it was not more than half
    Yes it did. It was over three years. So 11550 x 0.82^2 for the 2 years left

    £7766.22, so no more than half

    You can put 3.4 on the trolley but you have to round down so 3 is the answer

    b) 9/20=
    0.45
    2a. 5a*2b*3c =
    30abc
    b. Factorise fully 3y +6 =
    3(y+2)
    c. Expand x(x-3)=
    x^2-3x
    3.
    x=9.25
    4. Smallest packet was best value for money because it was cheapest per bag of crisps
    5. 4 times as many red than green: There were 0.4 blue and 0.15 yellow.
    0.4+0.15+4x+x=1
    0.55+5x=1
    5x=0.45
    x=0.09
    4x=0.36
    Green- 0.09 Red- 0.36
    6a. 20.3

    18. 10a^5b^4
    b. y= 5p^2-x
    19.11 males
    20. x= 0.29 or x= -2.29
    21. 29.25
    22. F.d- 1.6, 3.2, 2.4, 1.8, 0.3

    Its 3.7 not 3.8, in the exam i took them away from the needed number and 3.7 was like 3 tenths closer to it than 3.8
    3.75 gave the answer 33.98 etc.
    so the answer was between 3.75 and 3.8 so you round up

    It said THREE years so you had to times by 0.82 once more

    It's okay!! You'll only lose like 1mark :P you'll get a mark for the correct table
    Yeah. Silly mistakes I made:
    - Used radius instead of diameter for circle perimeter question.
    - Used 20 and 40 for lower and upper quartiles rather than 15 and 30 (doh!).
    - Got the question with the simplifying the algebraic fraction wrong.

    So all in all after realising these mistakes my confidence has taken a dip.

    youve got this right but forgot to do compound intrest as it was 18% for two years,after the first year where it was 23%,you should get 2 marks

    Did anyone else get 396 (or around there) at some point during the pentagon question?

    I did the exterior angles, then the interior ones. Calculated the two interior angles at the bottom, and the two right angles on the symmetrical lines (I think they were right angles)

    Finally did 540 - 396oraroundthere
    i got x = 144 i think dunnoo if its right

    Will I get 0 marks for that answer or maybe 1-2?
    If the calculations were correct for the numbers you used/the way you tried to do it, you'll probably get a few method marks but the number depends on how many marks that question was.

    But wasn't 3.75 closer than 3.7? I rounded it to 3.8 anyway because of that?
