50100 =
12 Diana spent: Diana's total = 1 : 2
Amount that Elyse spent
= 3 x 1 u
= 3 u
Amount that the three girls spent
= 1 u + 3 u + 109
= 4 u + 109
Amount that the three girls spent
= 1074 - 545
= $529
4 u + 109 = 529
4 u = 529 - 109
4 u = 420
1 u = 420 ÷ 4 = 105
Amount that Anna and Elyse had in the end
= 545 - 1 u
= 545 - 1 x 105
= 545 - 105
= $440
Answer(s): $440
