40% =
40100 =
25 Yoko spent: Yoko's total = 2 : 5
Amount that Gillian spent
= 4 x 2 u
= 8 u
Amount that the three girls spent
= 2 u + 8 u + 226
= 10 u + 226
Amount that the three girls spent
= 2350 - 764
= $1586
10 u + 226 = 1586
10 u = 1586 - 226
10 u = 1360
1 u = 1360 ÷ 10 = 136
Amount that Wendy and Gillian had in the end
= 764 - 3 u
= 764 - 3 x 136
= 764 - 408
= $356
Answer(s): $356
