40% =
40100 =
25 Opal spent: Opal's total = 2 : 5
Amount that Linda spent
= 4 x 2 u
= 8 u
Amount that the three girls spent
= 2 u + 8 u + 159
= 10 u + 159
Amount that the three girls spent
= 1552 - 463
= $1089
10 u + 159 = 1089
10 u = 1089 - 159
10 u = 930
1 u = 930 ÷ 10 = 93
Amount that Lucy and Linda had in the end
= 463 - 3 u
= 463 - 3 x 93
= 463 - 279
= $184
Answer(s): $184
