25 u |
28 u |

- 4x5 =
- 20 u |

After |
1 u |
1x5 =
5 u |

Comparing Ken
and Peter in the end |
1 u |
5 u |

The amount that Peter had in the end is the same. Make the amount that Peter had in the end the same. LCM of 1 and 5 is 5.
Total amount that Peter and Ken had at first
= 3 u + 25 u
= 28 u
28 u = 280
1 u = 280 ÷ 28 = 10
Amount that Peter had at first
= 25 u
= 25 x 10
= $250
Answer(s): $250
