12 Roshel spent: Roshel's total = 1 : 2
Amount that Penelope spent
= 4 x 1 u
= 4 u
Amount that the three girls spent
= 1 u + 4 u + 270
= 5 u + 270
Amount that the three girls spent
= 1738 - 478
= $1260
5 u + 270 = 1260
5 u = 1260 - 270
5 u = 990
1 u = 990 ÷ 5 = 198
Amount that Pamela and Penelope had in the end
= 478 - 1 u
= 478 - 1 x 198
= 478 - 198
= $280
Answer(s): $280
