20100 =
15 Yoko spent: Yoko's total = 1 : 5
Amount that Betty spent
= 2 x 1 u
= 2 u
Amount that the three girls spent
= 1 u + 2 u + 119
= 3 u + 119
Amount that the three girls spent
= 1264 - 767
= $497
3 u + 119 = 497
3 u = 497 - 119
3 u = 378
1 u = 378 ÷ 3 = 126
Amount that Opal and Betty had in the end
= 767 - 4 u
= 767 - 4 x 126
= 767 - 504
= $263
Answer(s): $263
