25100 =
14 Lucy spent: Lucy's total = 1 : 4
Amount that Zoe spent
= 4 x 1 u
= 4 u
Amount that the three girls spent
= 1 u + 4 u + 269
= 5 u + 269
Amount that the three girls spent
= 1112 - 553
= $559
5 u + 269 = 559
5 u = 559 - 269
5 u = 290
1 u = 290 ÷ 5 = 58
Amount that Betty and Zoe had in the end
= 553 - 3 u
= 553 - 3 x 58
= 553 - 174
= $379
Answer(s): $379
