25 The amount that Sabrina and Jen had left is the same. Make the amount that Sabrina and Jen had left is the same. LCM of 4 and 2 is 4.
Amount that Jen had at first = 9 u
Amount that Sabrina had at first = 10 u
Amount that Sabrina had more than Jen at first
= 10 u - 9 u
= 1 u
= $18
Amount that Jen had at first
= 9 u
= 9 x 18
= $162
