50% =
50100 =
12 Jean spent: Jean's total = 1 : 2
Amount that Abi spent
= 4 x 1 u
= 4 u
Amount that the three girls spent
= 1 u + 4 u + 235
= 5 u + 235
Amount that the three girls spent
= 1949 - 734
= $1215
5 u + 235 = 1215
5 u = 1215 - 235
5 u = 980
1 u = 980 ÷ 5 = 196
Amount that Zoe and Abi had in the end
= 734 - 1 u
= 734 - 1 x 196
= 734 - 196
= $538
Answer(s): $538
