12 Joelle spent: Joelle's total = 1 : 2
Amount that Xylia spent
= 4 x 1 u
= 4 u
Amount that the three girls spent
= 1 u + 4 u + 248
= 5 u + 248
Amount that the three girls spent
= 1299 - 461
= $838
5 u + 248 = 838
5 u = 838 - 248
5 u = 590
1 u = 590 ÷ 5 = 118
Amount that Tiffany and Xylia had in the end
= 461 - 1 u
= 461 - 1 x 118
= 461 - 118
= $343
Answer(s): $343
