Comparing Ethan
and Seth in the end |

The amount that Seth had in the end is the same. Make the amount that Seth had in the end the same. LCM of 1 and 4 is 4.
Total amount that Seth and Ethan had at first
= 6 u + 24 u
= 30 u
30 u = 780
1 u = 780 ÷ 30 = 26
Amount that Seth had at first
= 24 u
= 24 x 26
= $624
Answer(s): $624
