25% =
25100 =
14 Opal spent: Opal's total = 1 : 4
Amount that Jade spent
= 4 x 1 u
= 4 u
Amount that the three girls spent
= 1 u + 4 u + 145
= 5 u + 145
Amount that the three girls spent
= 1085 - 625
= $460
5 u + 145 = 460
5 u = 460 - 145
5 u = 315
1 u = 315 ÷ 5 = 63
Amount that Mary and Jade had in the end
= 625 - 3 u
= 625 - 3 x 63
= 625 - 189
= $436
Answer(s): $436
