S=Salma's money=5J; J=Justin's money=(1/5)S=(1/2)A; A=Ali's money=2J; T=total=$85
S+J+A=T Substitute for S and A
5J+J+2J=$85
8J=$85
J=$10.625 ANSWER 1: Justin has $10.63.
Salma=5J=5($10.625)=$53.13 ANSWER 2: Salma has $53.13
Ali=2J=2($10.625)=$21.25 ANSWER 3: Ali has $21.25
CHECK
S+J+A=$85.00
$53.13+$10.63+$21.25=$85.00
$85.01=$85.00 (discrepancy from rounding)
