**Reiny**, Sunday, May 5, 2013 at 11:15amJohn's number --- 8x

Dale's number --- 5x

Bob's number --- y

but Dale's = (10/13)Bob's

5x = (10/13)Bob

Bob = 5x(13/10) = 13x/2

finally:

8x + 5x + 13x/2 = 273

16x + 10x + 13x = 546

39x = 546

x = 14

John has 112

Dale has 70

Bob has 91

So John has 42 more than Dale
