50100 =
12 Winnie spent: Winnie's total = 1 : 2
Amount that Gem spent
= 4 x 1 u
= 4 u
Amount that the three girls spent
= 1 u + 4 u + 176
= 5 u + 176
Amount that the three girls spent
= 1798 - 622
= $1176
5 u + 176 = 1176
5 u = 1176 - 176
5 u = 1000
1 u = 1000 ÷ 5 = 200
Amount that Kathy and Gem had in the end
= 622 - 1 u
= 622 - 1 x 200
= 622 - 200
= $422
Answer(s): $422
