25100 =
14 Pamela spent: Pamela's total = 1 : 4
Amount that Xuan spent
= 4 x 1 u
= 4 u
Amount that the three girls spent
= 1 u + 4 u + 266
= 5 u + 266
Amount that the three girls spent
= 1556 - 550
= $1006
5 u + 266 = 1006
5 u = 1006 - 266
5 u = 740
1 u = 740 ÷ 5 = 148
Amount that Kathy and Xuan had in the end
= 550 - 3 u
= 550 - 3 x 148
= 550 - 444
= $106
Answer(s): $106
