Not reasonable. 3sf you shld know the meaning. Moreover, they
didnt say price must 2 dp. Thing is if it is 3sf it is actually not
very accurate.
Btw, i calculated every small mistake like me giving in 3
sf.
I minus 18 marks.
If unlucky, teacher strict, could be -20 XD
The issue about the figure for money is not about reasonable or
not reasonable.
The issue is that if everyone say the sun is blue... THEN the
sun is blue.
I am of the 3dp camp but I told my students to write solutions
to the nearest cent because the whole world say so. I asked teacher
friends and asked my students to ask their teachers about it and
mass majority insist on nearest cents.
If everyone say vandalism is not a crime then it is not a
crime.
If everyone say smoking is a crime then it is a crime.
This is how the world work. The exam board will definitely not
go against the majority.
That said, I am of the opinion that 3dp is ok according to the
letters of the instructions... but I don't try it.
