12 Jade spent: Jade's total = 1 : 2
Amount that Kylie spent
= 3 x 1 u
= 3 u
Amount that the three girls spent
= 1 u + 3 u + 257
= 4 u + 257
Amount that the three girls spent
= 1452 - 451
= $1001
4 u + 257 = 1001
4 u = 1001 - 257
4 u = 744
1 u = 744 ÷ 4 = 186
Amount that Olivia and Kylie had in the end
= 451 - 1 u
= 451 - 1 x 186
= 451 - 186
= $265
Answer(s): $265
