20100 =
15 Xandra spent: Xandra's total = 1 : 5
Amount that Ivory spent
= 3 x 1 u
= 3 u
Amount that the three girls spent
= 1 u + 3 u + 192
= 4 u + 192
Amount that the three girls spent
= 860 - 444
= $416
4 u + 192 = 416
4 u = 416 - 192
4 u = 224
1 u = 224 ÷ 4 = 56
Amount that Anna and Ivory had in the end
= 444 - 4 u
= 444 - 4 x 56
= 444 - 224
= $220
Answer(s): $220
