25100 =
14 Kimberly spent: Kimberly's total = 1 : 4
Amount that Dana spent
= 2 x 1 u
= 2 u
Amount that the three girls spent
= 1 u + 2 u + 272
= 3 u + 272
Amount that the three girls spent
= 899 - 405
= $494
3 u + 272 = 494
3 u = 494 - 272
3 u = 222
1 u = 222 ÷ 3 = 74
Amount that Diana and Dana had in the end
= 405 - 3 u
= 405 - 3 x 74
= 405 - 222
= $183
Answer(s): $183
