Total amount that Nicole and Sabrina had at first
= 5 u + 5 u + 20
= 10 u + 20
10 u + 20 = 460
5 u + 4 u = 460 - 20
10 u = 440
1 u = 440 ÷ 10 = 44
Amount that Nicole had at first
= 5 u
= 5 x 44
= $220
Amount that Sabrina had at first
= 460 - 220
= $240
At first
Nicole : Sabrina
220 : 240
11 : 12
Answer(s): 11 : 12
