40% =
40100 =
25 Emily spent: Emily's total = 2 : 5
Amount that Victoria spent
= 4 x 2 u
= 8 u
Amount that the three girls spent
= 2 u + 8 u + 200
= 10 u + 200
Amount that the three girls spent
= 1667 - 677
= $990
10 u + 200 = 990
10 u = 990 - 200
10 u = 790
1 u = 790 ÷ 10 = 79
Amount that Kathy and Victoria had in the end
= 677 - 3 u
= 677 - 3 x 79
= 677 - 237
= $440
Answer(s): $440
