If they saved £29 all together, and if each of them saved the same amount,
then each saved £29/4 = £7.25 or £7 and 25p.
(Before decimalization in 1971, £7.25 would have been £7 and 5s .)
It would be bigger than 1/2 inches because they are simply asking for the difference which is 5 1/2-5= 1/2.

Also, Rex should find a different pool because that fee is ridiculous.
2x - 1 + 3x = 0
2x + 3x - 1 = 0
(2 + 3)x - 1 = 0
5x - 1 = 0
14:18 is an equivalent ratio!
