30% =
30100 =
310 Eva spent: Eva's total = 3 : 10
Amount that Kimberly spent
= 3 x 3 u
= 9 u
Amount that the three girls spent
= 3 u + 9 u + 281
= 12 u + 281
Amount that the three girls spent
= 2018 - 777
= $1241
12 u + 281 = 1241
12 u = 1241 - 281
12 u = 960
1 u = 960 ÷ 12 = 80
Amount that Xuan and Kimberly had in the end
= 777 - 7 u
= 777 - 7 x 80
= 777 - 560
= $217
Answer(s): $217
