Hi, my brain is aching somewhat over what I am sure is straight forward but I can't see the wood for the trees...help would be appreciated!
A simple little question really; I am going on holiday with friends (there are 4 couples), and the total for 7 nights is £725. 2 couples are staying 3 nights, one couple 6 nights, and the other couple all 7 nights.
If you look at a nightly cost (ie £725/7) it is £103.57 per night. Clearly by just splitting this up on a nightly basis (ie 4 ways for 3 nights, 2 ways for the next 3 nights, then one way for the last night) will result in the couple staying for 7 nights paying disproportionately more (in fact the 2 couples staying for 3 nights only pay £77.68!)
How can we weight it so that the amounts paid are fairer?
(OK, not strictly homework, but maths nontheless!)
