35 =
25 Fraction of money that Lynn had left
= 1 -
23 =
13 The amount that Lynn and Joelle had left is the same. Make the amount that Lynn and Joelle had left is the same. LCM of 2 and 1 is 2.
Amount that Joelle had at first = 5 u
Amount that Lynn had at first = 6 u
Amount that Lynn had more than Joelle at first
= 6 u - 5 u
= 1 u
= $22
Amount that Joelle had at first
= 5 u
= 5 x 22
= $110
Answer(s): $110
