40% =
40100 =
25 Risa spent: Risa's total = 2 : 5
Amount that Jen spent
= 2 x 2 u
= 4 u
Amount that the three girls spent
= 2 u + 4 u + 256
= 6 u + 256
Amount that the three girls spent
= 1658 - 634
= $1024
6 u + 256 = 1024
6 u = 1024 - 256
6 u = 768
1 u = 768 ÷ 6 = 128
Amount that Yoko and Jen had in the end
= 634 - 3 u
= 634 - 3 x 128
= 634 - 384
= $250
Answer(s): $250
