50% =
50100 =
12 Dana spent: Dana's total = 1 : 2
Amount that Joelle spent
= 2 x 1 u
= 2 u
Amount that the three girls spent
= 1 u + 2 u + 149
= 3 u + 149
Amount that the three girls spent
= 1175 - 564
= $611
3 u + 149 = 611
3 u = 611 - 149
3 u = 462
1 u = 462 ÷ 3 = 154
Amount that Jean and Joelle had in the end
= 564 - 1 u
= 564 - 1 x 154
= 564 - 154
= $410
Answer(s): $410
