25 Yen and Marion had the same amount of money in the end. Make the amount that each had in the end the same. LCM of 1 and 3 is 3.
Amount that Yen had less than Marion at first
= 15 u - 5 u
= 10 u
10 u = 150
1 u = 150 ÷ 10 = 15
Amount that Marion had at first
= 15 u
= 15 x 15
= $225
Answer(s): $225
