Eric spent $15 on a dress. He spent
15 of his remaining money on a vest. If he still had
25 of his money left, how much did he have at first?

| $15 |

4 |
| 3x2 |
2x2 |
| 5 u |
1 u |
4 u |
The amount that Eric had left is the same. Make the numerators the same. LCM of 2 and 4 is 4.
2x25x2 of his money =
45 of his remaining money
410 of his money =
45 of his remaining money
Amount that Eric spent on the dress = 5 u
5 u = 15
1 u = 15 ÷ 5 = 3
Amount that Eric had at first
= 10 u
= 10 x 3
= $30
Answer(s): $30
