20100 =
15 Kathy spent: Kathy's total = 1 : 5
Amount that Tina spent
= 3 x 1 u
= 3 u
Amount that the three girls spent
= 1 u + 3 u + 214
= 4 u + 214
Amount that the three girls spent
= 1333 - 727
= $606
4 u + 214 = 606
4 u = 606 - 214
4 u = 392
1 u = 392 ÷ 4 = 98
Amount that Hilda and Tina had in the end
= 727 - 4 u
= 727 - 4 x 98
= 727 - 392
= $335
Answer(s): $335
