40% =
40100 =
25 Jen spent: Jen's total = 2 : 5
Amount that Dana spent
= 4 x 2 u
= 8 u
Amount that the three girls spent
= 2 u + 8 u + 146
= 10 u + 146
Amount that the three girls spent
= 1665 - 459
= $1206
10 u + 146 = 1206
10 u = 1206 - 146
10 u = 1060
1 u = 1060 ÷ 10 = 106
Amount that Zara and Dana had in the end
= 459 - 3 u
= 459 - 3 x 106
= 459 - 318
= $141
Answer(s): $141
