25 The amount that Wendy and Kathy had left is the same. Make the amount that Wendy and Kathy had left is the same. LCM of 4 and 2 is 4.
Amount that Kathy had at first = 9 u
Amount that Wendy had at first = 10 u
Amount that Wendy had more than Kathy at first
= 10 u - 9 u
= 1 u
= $29
Amount that Kathy had at first
= 9 u
= 9 x 29
= $261
