50% =
50100 =
12 Abi spent: Abi's total = 1 : 2
Amount that Yoko spent
= 4 x 1 u
= 4 u
Amount that the three girls spent
= 1 u + 4 u + 198
= 5 u + 198
Amount that the three girls spent
= 1524 - 581
= $943
5 u + 198 = 943
5 u = 943 - 198
5 u = 745
1 u = 745 ÷ 5 = 149
Amount that Ivory and Yoko had in the end
= 581 - 1 u
= 581 - 1 x 149
= 581 - 149
= $432
Answer(s): $432
