Total amount that Nora and Gillian had at first
= 4 u + 4 u + 48
= 8 u + 48
8 u + 48 = 224
4 u + 3 u = 224 - 48
8 u = 176
1 u = 176 ÷ 8 = 22
Amount that Nora had at first
= 4 u
= 4 x 22
= $88
Amount that Gillian had at first
= 224 - 88
= $136
At first
Nora : Gillian
88 : 136
11 : 17
Answer(s): 11 : 17
