Seth spent $90 on a skirt. He spent
17 of his remaining money on a dress. If he still had
38 of his money left, how much did he have at first?
| Skirt |
Remaining amount |

Dress |
Left |
| $90 |
1 |
6 |
| 5x2 |
3x2 |
| 9 u |
1 u |
6 u |
The amount that Seth had left is the same. Make the numerators the same. LCM of 3 and 6 is 6.
3x28x2 of his money =
67 of his remaining money
616 of his money =
67 of his remaining money
Amount that Seth spent on the skirt = 9 u
9 u = 90
1 u = 90 ÷ 9 = 10
Amount that Seth had at first
= 16 u
= 16 x 10
= $160
Answer(s): $160
