50% =
50100 =
12 Ivory spent: Ivory's total = 1 : 2
Amount that Gillian spent
= 3 x 1 u
= 3 u
Amount that the three girls spent
= 1 u + 3 u + 195
= 4 u + 195
Amount that the three girls spent
= 1221 - 514
= $707
4 u + 195 = 707
4 u = 707 - 195
4 u = 512
1 u = 512 ÷ 4 = 128
Amount that Rachel and Gillian had in the end
= 514 - 1 u
= 514 - 1 x 128
= 514 - 128
= $386
Answer(s): $386
