25% =
25100 =
14 Jen spent: Jen's total = 1 : 4
Amount that Barbara spent
= 4 x 1 u
= 4 u
Amount that the three girls spent
= 1 u + 4 u + 247
= 5 u + 247
Amount that the three girls spent
= 1425 - 633
= $792
5 u + 247 = 792
5 u = 792 - 247
5 u = 545
1 u = 545 ÷ 5 = 109
Amount that Gabby and Barbara had in the end
= 633 - 3 u
= 633 - 3 x 109
= 633 - 327
= $306
Answer(s): $306
