25% =
25100 =
14 Erika spent: Erika's total = 1 : 4
Amount that Anna spent
= 4 x 1 u
= 4 u
Amount that the three girls spent
= 1 u + 4 u + 175
= 5 u + 175
Amount that the three girls spent
= 948 - 458
= $490
5 u + 175 = 490
5 u = 490 - 175
5 u = 315
1 u = 315 ÷ 5 = 63
Amount that Nora and Anna had in the end
= 458 - 3 u
= 458 - 3 x 63
= 458 - 189
= $269
Answer(s): $269
