12 Barbara spent: Barbara's total = 1 : 2
Amount that Fanny spent
= 2 x 1 u
= 2 u
Amount that the three girls spent
= 1 u + 2 u + 266
= 3 u + 266
Amount that the three girls spent
= 885 - 409
= $476
3 u + 266 = 476
3 u = 476 - 266
3 u = 210
1 u = 210 ÷ 3 = 70
Amount that Tammy and Fanny had in the end
= 409 - 1 u
= 409 - 1 x 70
= 409 - 70
= $339
Answer(s): $339
