Paul spent $27 on a vest. He spent
15 of his remaining money on a shirt. If he still had
27 of his money left, how much did he have at first?

| $27 |

4 |
| 5x2 |
2x2 |
| 9 u |
1 u |
4 u |
The amount that Paul had left is the same. Make the numerators the same. LCM of 2 and 4 is 4.
2x27x2 of his money =
45 of his remaining money
414 of his money =
45 of his remaining money
Amount that Paul spent on the vest = 9 u
9 u = 27
1 u = 27 ÷ 9 = 3
Amount that Paul had at first
= 14 u
= 14 x 3
= $42
Answer(s): $42
