Tommy spent $90 on a jacket. He spent
17 of his remaining money on a sweater. If he still had
38 of his money left, how much did he have at first?

| $90 |

6 |
| 5x2 |
3x2 |
| 9 u |
1 u |
6 u |
The amount that Tommy 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 Tommy spent on the jacket = 9 u
9 u = 90
1 u = 90 ÷ 9 = 10
Amount that Tommy had at first
= 16 u
= 16 x 10
= $160
Answer(s): $160
