15 The amount that Vanessa and Emma had left is the same. Make the amount that Vanessa and Emma had left is the same. LCM of 2 and 1 is 2.
Amount that Emma had at first = 9 u
Amount that Vanessa had at first = 10 u
Amount that Vanessa had more than Emma at first
= 10 u - 9 u
= 1 u
= $28
Amount that Emma had at first
= 9 u
= 9 x 28
= $252
