Fraction of money that Xandra had left
= 1 -
35 =
25 Fraction of money that Wendy had left
= 1 -
23 =
13 The amount that Wendy and Xandra had left is the same. Make the amount that Wendy and Xandra had left is the same. LCM of 2 and 1 is 2.
Amount that Xandra had at first = 5 u
Amount that Wendy had at first = 6 u
Amount that Wendy had more than Xandra at first
= 6 u - 5 u
= 1 u
= $21
Amount that Xandra had at first
= 5 u
= 5 x 21
= $105
Answer(s): $105
