Edexcel GCSE Linear Foundation Tier Calculator

24. Trial and improvement
1.9 (4 marks)

Would 1.85 be incorrect? I put it because I thought it was closer :/ If so how many marks would I lose? I had loads of working out e.g

1 =
2 =
1.5 =
1.7 =
1.8 =
1.85 =
1.9 =

I said
"1.9*1.9*1.9 = 6.859
10*1.9=19
6.859+19=25.859
x=1.9"
Would I still get the full marks even though I did not write it out as a trail and improvement table?

Mr M can you please tell me the exact number of marks needed for a grade C in each paper ?

Also for the trial and improvement question my final answer was 1.8 would i get a mark for it ? An i showed all my working out too so how many marks would I get ?
