50100 =
12 Natalie spent: Natalie's total = 1 : 2
Amount that Dana spent
= 2 x 1 u
= 2 u
Amount that the three girls spent
= 1 u + 2 u + 153
= 3 u + 153
Amount that the three girls spent
= 1303 - 775
= $528
3 u + 153 = 528
3 u = 528 - 153
3 u = 375
1 u = 375 ÷ 3 = 125
Amount that Barbara and Dana had in the end
= 775 - 1 u
= 775 - 1 x 125
= 775 - 125
= $650
Answer(s): $650
