25100 =
14 Jade spent: Jade's total = 1 : 4
Amount that Jane spent
= 2 x 1 u
= 2 u
Amount that the three girls spent
= 1 u + 2 u + 128
= 3 u + 128
Amount that the three girls spent
= 1412 - 723
= $689
3 u + 128 = 689
3 u = 689 - 128
3 u = 561
1 u = 561 ÷ 3 = 187
Amount that Winnie and Jane had in the end
= 723 - 3 u
= 723 - 3 x 187
= 723 - 561
= $162
Answer(s): $162
