25 Sabrina spent: Sabrina's total = 2 : 5
Amount that Olivia spent
= 4 x 2 u
= 8 u
Amount that the three girls spent
= 2 u + 8 u + 272
= 10 u + 272
Amount that the three girls spent
= 1374 - 452
= $922
10 u + 272 = 922
10 u = 922 - 272
10 u = 650
1 u = 650 ÷ 10 = 65
Amount that Usha and Olivia had in the end
= 452 - 3 u
= 452 - 3 x 65
= 452 - 195
= $257
Answer(s): $257
