Perry spent $21 on a jacket. He spent
17 of his remaining money on a skirt. If he still had
37 of his money left, how much did he have at first?
| Jacket |

| $21 |
1 |
6 |
| 4x2 |
3x2 |
| 7 u |
1 u |
6 u |
The amount that Perry 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 Perry spent on the jacket = 7 u
7 u = 21
1 u = 21 ÷ 7 = 3
Amount that Perry had at first
= 14 u
= 14 x 3
= $42
Answer(s): $42
