50% =
50100 =
12 Jade spent: Jade's total = 1 : 2
Amount that Yen spent
= 3 x 1 u
= 3 u
Amount that the three girls spent
= 1 u + 3 u + 139
= 4 u + 139
Amount that the three girls spent
= 1263 - 672
= $591
4 u + 139 = 591
4 u = 591 - 139
4 u = 452
1 u = 452 ÷ 4 = 113
Amount that Joelle and Yen had in the end
= 672 - 1 u
= 672 - 1 x 113
= 672 - 113
= $559
Answer(s): $559
