15 Fanny and Julie had the same amount of money in the end. Make the amount that each had in the end the same. LCM of 3 and 4 is 12.
Amount that Fanny had less than Julie at first
= 20 u - 15 u
= 5 u
5 u = 120
1 u = 120 ÷ 5 = 24
Amount that Julie had at first
= 20 u
= 20 x 24
= $480
Answer(s): $480
