Ken spent $120 on a vest. He spent
17 of his remaining money on a dress. If he still had
25 of his money left, how much did he have at first?
| Vest |

| $120 |

6 |
| 3x3 |
2x3 |
| 8 u |
1 u |
6 u |
The amount that Ken had left is the same. Make the numerators the same. LCM of 2 and 6 is 6.
2x35x3 of his money =
67 of his remaining money
615 of his money =
67 of his remaining money
Amount that Ken spent on the vest = 8 u
8 u = 120
1 u = 120 ÷ 8 = 15
Amount that Ken had at first
= 15 u
= 15 x 15
= $225
Answer(s): $225
