25100 =
14 Jean spent: Jean's total = 1 : 4
Amount that Kathy spent
= 4 x 1 u
= 4 u
Amount that the three girls spent
= 1 u + 4 u + 180
= 5 u + 180
Amount that the three girls spent
= 1111 - 571
= $540
5 u + 180 = 540
5 u = 540 - 180
5 u = 360
1 u = 360 ÷ 5 = 72
Amount that Gillian and Kathy had in the end
= 571 - 3 u
= 571 - 3 x 72
= 571 - 216
= $355
Answer(s): $355
