14 Emma spent: Emma's total = 1 : 4
Amount that Xylia spent
= 2 x 1 u
= 2 u
Amount that the three girls spent
= 1 u + 2 u + 210
= 3 u + 210
Amount that the three girls spent
= 1541 - 752
= $789
3 u + 210 = 789
3 u = 789 - 210
3 u = 579
1 u = 579 ÷ 3 = 193
Amount that Nicole and Xylia had in the end
= 752 - 3 u
= 752 - 3 x 193
= 752 - 579
= $173
Answer(s): $173
