Luis spent $35 on a blazer. He spent
19 of his remaining money on a blouse. If he still had
47 of his money left, how much did he have at first?
| Blazer |
Remaining amount |

Blouse |
Left |
| $35 |
1 |
8 |
| 3x2 |
4x2 |
| 5 u |
1 u |
8 u |
The amount that Luis 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 Luis spent on the blazer = 5 u
5 u = 35
1 u = 35 ÷ 5 = 7
Amount that Luis had at first
= 14 u
= 14 x 7
= $98
Answer(s): $98
