Answer in the range 14 to 16 inclusive.
1
(b)
An explanation which recognises that the bar for tomato is shorter than
the other two bars added together, eg
•
‘Because there are 300 children altogether and only 135 chose tomato’;
•
‘Because 165 is more than 135’;
•
‘Because double 135 is 270 and there are more children than that altogether’;
•
‘Because half of 300 is 150’;
•
‘Because tomato is less than mushroom add chicken’.
No mark is awarded for writing ‘No’ alone.
Do not accept vague or arbitrary explanations, eg
•
‘Because most of the children chose tomato’;
•
‘Because 135 children chose tomato’;
•
‘Because 75 + 135 + 90 = 300’.
If ‘Yes’ is circled but a correct, unambiguous explanation is given
then award the mark.
