35 =
25 The amount that Sarah and Nicole had left is the same. Make the amount that Sarah and Nicole had left is the same. LCM of 4 and 2 is 4.
Amount that Nicole had at first = 9 u
Amount that Sarah had at first = 10 u
Amount that Sarah had more than Nicole at first
= 10 u - 9 u
= 1 u
= $22
Amount that Nicole had at first
= 9 u
= 9 x 22
= $198
