12 Fraction of money that Tiffany had left
= 1 -
35 =
25 The amount that Tiffany and Lucy had left is the same. Make the amount that Tiffany and Lucy had left is the same. LCM of 1 and 2 is 2.
Amount that Lucy had at first = 2 u
Amount that Tiffany had at first = 5 u
Amount that Tiffany had more than Lucy at first
= 5 u - 2 u
= 1 u
= $27
Amount that Lucy had at first
= 2 u
= 2 x 27
= $54
Answer(s): $54
