40% =
40100 =
25 Risa spent: Risa's total = 2 : 5
Amount that Usha spent
= 2 x 2 u
= 4 u
Amount that the three girls spent
= 2 u + 4 u + 141
= 6 u + 141
Amount that the three girls spent
= 1971 - 756
= $1215
6 u + 141 = 1215
6 u = 1215 - 141
6 u = 1074
1 u = 1074 ÷ 6 = 179
Amount that Emma and Usha had in the end
= 756 - 3 u
= 756 - 3 x 179
= 756 - 537
= $219
Answer(s): $219
