12 Tiffany spent: Tiffany's total = 1 : 2
Amount that Kathy spent
= 2 x 1 u
= 2 u
Amount that the three girls spent
= 1 u + 2 u + 106
= 3 u + 106
Amount that the three girls spent
= 1166 - 652
= $514
3 u + 106 = 514
3 u = 514 - 106
3 u = 408
1 u = 408 ÷ 3 = 136
Amount that Joelle and Kathy had in the end
= 652 - 1 u
= 652 - 1 x 136
= 652 - 136
= $516
Answer(s): $516
