6x3 =
18 u |
25 u |
Change |
- 6 u |
- 5x3 =
- 15 u |

After |
1 u |
1x3 =
3 u |

Comparing Charlie
and Zeph in the end |
1 u |
3 u |

The amount that Zeph had in the end is the same. Make the amount that Zeph had in the end the same. LCM of 1 and 3 is 3.
Total amount that Zeph and Charlie had at first
= 7 u + 18 u
= 25 u
25 u = 425
1 u = 425 ÷ 25 = 17
Amount that Zeph had at first
= 18 u
= 18 x 17
= $306
Answer(s): $306
