25100 =
14 Tiffany spent: Tiffany's total = 1 : 4
Amount that Xylia spent
= 4 x 1 u
= 4 u
Amount that the three girls spent
= 1 u + 4 u + 200
= 5 u + 200
Amount that the three girls spent
= 1294 - 539
= $755
5 u + 200 = 755
5 u = 755 - 200
5 u = 555
1 u = 555 ÷ 5 = 111
Amount that Shiyun and Xylia had in the end
= 539 - 3 u
= 539 - 3 x 111
= 539 - 333
= $206
Answer(s): $206
