Ryan spent $90 on a shirt. He spent
19 of his remaining money on a coat. If he still had
47 of his money left, how much did he have at first?
| Shirt |
Remaining amount |

Coat |
Left |
| $90 |
1 |
8 |
| 3x2 |
4x2 |
| 5 u |
1 u |
8 u |
The amount that Ryan had left is the same. Make the numerators the same. LCM of 4 and 8 is 8.
4x27x2 of his money =
89 of his remaining money
814 of his money =
89 of his remaining money
Amount that Ryan spent on the shirt = 5 u
5 u = 90
1 u = 90 ÷ 5 = 18
Amount that Ryan had at first
= 14 u
= 14 x 18
= $252
Answer(s): $252
