25% =
25100 =
14 Zara spent: Zara's total = 1 : 4
Amount that Gillian spent
= 3 x 1 u
= 3 u
Amount that the three girls spent
= 1 u + 3 u + 230
= 4 u + 230
Amount that the three girls spent
= 1351 - 697
= $654
4 u + 230 = 654
4 u = 654 - 230
4 u = 424
1 u = 424 ÷ 4 = 106
Amount that Shiyun and Gillian had in the end
= 697 - 3 u
= 697 - 3 x 106
= 697 - 318
= $379
Answer(s): $379
