20% =
20100 =
15 Shiyun spent: Shiyun's total = 1 : 5
Amount that Gabby spent
= 2 x 1 u
= 2 u
Amount that the three girls spent
= 1 u + 2 u + 202
= 3 u + 202
Amount that the three girls spent
= 1168 - 636
= $532
3 u + 202 = 532
3 u = 532 - 202
3 u = 330
1 u = 330 ÷ 3 = 110
Amount that Nicole and Gabby had in the end
= 636 - 4 u
= 636 - 4 x 110
= 636 - 440
= $196
Answer(s): $196
