How much did John pay for lentils

[Dobybert]

I'm waiting to hear back from my tutor, for the meantime I would like to hear, how much is it for the canned lentils?

You’re on a roll tonight 😁

If I were going round the shop keeping a running total I may well say 87p, call it £1, so that's £7

But I'd be thinking 7 x 13 p (the difference between £1 and 87 p) is nearly £1 so that's £6 not £7 (you've more than accounted for the 9 p by calling your £1.90 worth of apples £2).

So there isn't a definitive answer and they need to accept either £6 or £7 or write the question more clearly, depending on what they're actually trying to achieve.

That is true, but with enough shopping buying 6 other things at £1.10 each would counter balance. (And if shopping I prefer to over estimate the price not underestimate.)

Without seeing the exact question I agree it is unclear.
I don't like online maths.

With L2 some answers ask you to estimate some answers. I know this because I’ve just done it.

It was bloody awful 😬

Most people are going to realise it's 87p per can. I mean I doubt it's per lentil. Can't see the issue here

Have you read the thread?

It is (ball-park) what lentils cost. The figures should surely be somewhere near realistic. And yes, I've read the whole thread. The question is poorly and ambiguously worded. Rounding up a unit price (87p to £1) is smart thinking if you want an approx total cost by mental arithmetic, but very bad practice from the pure maths point of view.
