| Change |
- 1x3 =
- 3 u |
- 2x2 =
- 4 u |
|
| After |
2x3 =
6 u |
1x2 =
2 u |

Comparing Ethan
and Neave in the end |
3x2 =
6 u |
1x2 =
2 u |

The amount that Ethan had in the end is repeated. Make the amount that Ethan had in the end the same. LCM of 2 and 3 is 6.
Total amount that Ethan and Neave had at first
= 9 u + 6 u
= 15 u
15 u = 555
1 u = 555 ÷ 15 = 37
Amount that Neave had at first
= 6 u
= 6 x 37
= $222
Answer(s): $222
