49 =
59 Fraction of money that Joelle had left
= 1 -
12 =
12 The amount that Joelle and Lucy had left is the same. Make the amount that Joelle and Lucy had left is the same. LCM of 5 and 1 is 5.
Amount that Lucy had at first = 9 u
Amount that Joelle had at first = 10 u
Amount that Joelle had more than Lucy at first
= 10 u - 9 u
= 1 u
= $19
Amount that Lucy had at first
= 9 u
= 9 x 19
= $171
Answer(s): $171
