Ahmad spent $105 on a skirt. He spent
17 of his remaining money on a sweater. If he still had
37 of his money left, how much did he have at first?
| Skirt |

| $105 |
1 |
6 |
| 4x2 |
3x2 |
| 7 u |
1 u |
6 u |
The amount that Ahmad had left is the same. Make the numerators the same. LCM of 3 and 6 is 6.
3x27x2 of his money =
67 of his remaining money
614 of his money =
67 of his remaining money
Amount that Ahmad spent on the skirt = 7 u
7 u = 105
1 u = 105 ÷ 7 = 15
Amount that Ahmad had at first
= 14 u
= 14 x 15
= $210
Answer(s): $210
