Sorry, took me so long to work that out that several posts have now made it clear! grin

Enjoy!

But 1440 x 32p = £4.6080

1440 x 31.3p + £4.50072

So Sainsbury's is right. I think...confused

Or it could be a genuine mistake ( yer never know!)

Sorry, I should have said rounded it down, they probably think it sounds more sciencey that way.

1440 X 31.3 = 45072

No, they haven't rounded it up Roses they have claimed it is 31.3p per 100 sheet when in fact it's 32p per 100 sheets.

(Left out the 100 sheets bit in the OP)

My maths is very ropey, but....

Done it the other way to check &

1440 x 31.3 = £4.4572

1440 x 32 = £4.6080

so does that somehow makes 31.3p per sheet nearer? confused

They have rounded it up a bit? Anya, I am shocked that anyone does the maths for all that shops claim ( and a bit impressed as well!) grinIt's as much as I can do this week to remember to actually buy them.

Have I got the maths wrong somewhere?

In case the photo isn't clear it says the pack contains 9 rolls with 160 'sheets' in each roll.

9x160 = 1440 (sheets)

1440 / 4.5 = 32

So why do Sainsburys think this equates to 31.3p per sheet? hmm
