Total amount that Pamela and Tina had at first
= 6 u + 3 u + 27
= 9 u + 27
9 u + 27 = 675
6 u + 5 u = 675 - 27
9 u = 648
1 u = 648 ÷ 9 = 72
Amount that Pamela had at first
= 6 u
= 6 x 72
= $432
Amount that Tina had at first
= 675 - 432
= $243
At first
Pamela : Tina
432 : 243
16 : 9
Answer(s): 16 : 9
