Total amount that Irene and Pamela had at first
= 5 u + 5 u + 85
= 10 u + 85
10 u + 85 = 595
5 u + 4 u = 595 - 85
10 u = 510
1 u = 510 ÷ 10 = 51
Amount that Irene had at first
= 5 u
= 5 x 51
= $255
Amount that Pamela had at first
= 595 - 255
= $340
At first
Irene : Pamela
255 : 340
3 : 4
Answer(s): 3 : 4
