50% =
50100 =
12 Shannon spent: Shannon's total = 1 : 2
Amount that Nora spent
= 2 x 1 u
= 2 u
Amount that the three girls spent
= 1 u + 2 u + 140
= 3 u + 140
Amount that the three girls spent
= 975 - 544
= $431
3 u + 140 = 431
3 u = 431 - 140
3 u = 291
1 u = 291 ÷ 3 = 97
Amount that Tina and Nora had in the end
= 544 - 1 u
= 544 - 1 x 97
= 544 - 97
= $447
Answer(s): $447
