Title: break even confusion
Post by: kriptik on October 04, 2010, 03:25:49 pm

when I solve part C of the question, do I leave it as it is(5.8)  or do I round up/down ?

Round up, you can't have 4.5 mobiles for example, they must be whole(in order to break even).

but if we round up, wouldn't it be considered as profit and not breaking even?

i did this

R= 5.5x
C= 3.4x+12.2

making R=C

5.5x=3.4x+12.2
2.1x=12.2
x=5.81
now if i round this up it would be considered as Martha making a profit. So do i just leave it as 5.81 phones?

you can't have .81 of a phone so you have to go down to x=5
what we were told last year in fm, roundinf off doesnt always work in logical answers =P

That's what i did, I'm preety sure you have to round up because a similar question to this came up in my sac and the teacher said you must round up, if you round down she won't break even.

round up
if you round down you won't break even (as above said)
break even is either on the dollar or profit

round up although its profit, its also breaking even. where as rounding down is just a loss.

Also "break" means to pass. It doesn't necessarily mean equate to. It just refers the the point where the income literally 'passes' the even point.
Common sense really 8)

break even is an accouting term it means how many mobiles does he martha have to sell to make no profit but no loss. 0 dollers.

For simplicities sake, just round up.

hey stonecold you got 48 in further, how many marks did you lose over both exams to end up with that mark? i would really like to know, thanks.

Title: Re: break even confusion
Post by: stonecold on October 06, 2010, 07:15:09 pm

I didn't get a statement of marks, but I know it was at least 2 from reading the examiners report.  I knew about those mistakes literally moments after walking out of the exam anyway...

I don't know if I made any other mistakes.  Possibly lost another mark or 2 at absolute most.

wow, so its true that 1 mark lost is one study score.

Strength of the cohort probably comes into it as well... I should have got a statement of marks. I really want to know exactly what I got...
