Total amount that Lynn and Pamela had at first
= 5 u + 3 u + 48
= 8 u + 48
8 u + 48 = 360
5 u + 4 u = 360 - 48
8 u = 312
1 u = 312 ÷ 8 = 39
Amount that Lynn had at first
= 5 u
= 5 x 39
= $195
Amount that Pamela had at first
= 360 - 195
= $165
At first
Lynn : Pamela
195 : 165
13 : 11
Answer(s): 13 : 11
