25% =
25100 =
14 Emily spent: Emily's total = 1 : 4
Amount that Lynn spent
= 3 x 1 u
= 3 u
Amount that the three girls spent
= 1 u + 3 u + 221
= 4 u + 221
Amount that the three girls spent
= 1015 - 582
= $433
4 u + 221 = 433
4 u = 433 - 221
4 u = 212
1 u = 212 ÷ 4 = 53
Amount that Irene and Lynn had in the end
= 582 - 3 u
= 582 - 3 x 53
= 582 - 159
= $423
Answer(s): $423
