25 Yen and Esther 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 Esther at first
= 15 u - 5 u
= 10 u
10 u = 230
1 u = 230 ÷ 10 = 23
Amount that Esther had at first
= 15 u
= 15 x 23
= $345
Answer(s): $345
