Billy spent $16 on a jacket. He spent
17 of his remaining money on a sweater. If he still had
25 of his money left, how much did he have at first?
| Jacket |
Remaining amount |

Sweater |
Left |
| $16 |
1 |
6 |
| 3x3 |
2x3 |
| 8 u |
1 u |
6 u |
The amount that Billy 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 Billy spent on the jacket = 8 u
8 u = 16
1 u = 16 ÷ 8 = 2
Amount that Billy had at first
= 15 u
= 15 x 2
= $30
Answer(s): $30
