50100 =
12 Xylia spent: Xylia's total = 1 : 2
Amount that Hilda spent
= 2 x 1 u
= 2 u
Amount that the three girls spent
= 1 u + 2 u + 287
= 3 u + 287
Amount that the three girls spent
= 1211 - 492
= $719
3 u + 287 = 719
3 u = 719 - 287
3 u = 432
1 u = 432 ÷ 3 = 144
Amount that Gabby and Hilda had in the end
= 492 - 1 u
= 492 - 1 x 144
= 492 - 144
= $348
Answer(s): $348
