15 Sabrina spent: Sabrina's total = 1 : 5
Amount that Lynn spent
= 3 x 1 u
= 3 u
Amount that the three girls spent
= 1 u + 3 u + 122
= 4 u + 122
Amount that the three girls spent
= 1284 - 654
= $630
4 u + 122 = 630
4 u = 630 - 122
4 u = 508
1 u = 508 ÷ 4 = 127
Amount that Xylia and Lynn had in the end
= 654 - 4 u
= 654 - 4 x 127
= 654 - 508
= $146
Answer(s): $146
