Ryan spent $90 on a shirt. He spent
15 of his remaining money on a sweater. If he still had
27 of his money left, how much did he have at first?
| Shirt |

| $90 |
1 |
4 |
| 5x2 |
2x2 |
| 9 u |
1 u |
4 u |
The amount that Ryan 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 Ryan spent on the shirt = 9 u
9 u = 90
1 u = 90 ÷ 9 = 10
Amount that Ryan had at first
= 14 u
= 14 x 10
= $140
Answer(s): $140
