50100 =
12 Hilda spent: Hilda's total = 1 : 2
Amount that Gillian spent
= 3 x 1 u
= 3 u
Amount that the three girls spent
= 1 u + 3 u + 168
= 4 u + 168
Amount that the three girls spent
= 1332 - 436
= $896
4 u + 168 = 896
4 u = 896 - 168
4 u = 728
1 u = 728 ÷ 4 = 182
Amount that Anna and Gillian had in the end
= 436 - 1 u
= 436 - 1 x 182
= 436 - 182
= $254
Answer(s): $254
