35 =
25 The amount that Nicole and Sarah had left is the same. Make the amount that Nicole and Sarah had left is the same. LCM of 3 and 2 is 6.
Amount that Sarah had at first = 7 u
Amount that Nicole had at first = 15 u
Amount that Nicole had more than Sarah at first
= 15 u - 7 u
= 1 u
= $23
Amount that Sarah had at first
= 7 u
= 7 x 23
= $161
