30% =
30100 =
310 Anna spent: Anna's total = 3 : 10
Amount that Usha spent
= 2 x 3 u
= 6 u
Amount that the three girls spent
= 3 u + 6 u + 276
= 9 u + 276
Amount that the three girls spent
= 1771 - 721
= $1050
9 u + 276 = 1050
9 u = 1050 - 276
9 u = 774
1 u = 774 ÷ 9 = 86
Amount that Gwen and Usha had in the end
= 721 - 7 u
= 721 - 7 x 86
= 721 - 602
= $119
Answer(s): $119
