25% =
25100 =
14 Irene spent: Irene's total = 1 : 4
Amount that Jen spent
= 4 x 1 u
= 4 u
Amount that the three girls spent
= 1 u + 4 u + 154
= 5 u + 154
Amount that the three girls spent
= 1028 - 609
= $419
5 u + 154 = 419
5 u = 419 - 154
5 u = 265
1 u = 265 ÷ 5 = 53
Amount that Linda and Jen had in the end
= 609 - 3 u
= 609 - 3 x 53
= 609 - 159
= $450
Answer(s): $450
