Liam spent $45 on a shirt. He spent
19 of his remaining money on a blouse. If he still had
49 of his money left, how much did he have at first?
| Shirt |
Remaining amount |
| |
Blouse |
Left |
| $45 |
1 |
8 |
| 5x2 |
4x2 |
| 9 u |
1 u |
8 u |
The amount that Liam had left is the same. Make the numerators the same. LCM of 4 and 8 is 8.
4x29x2 of his money =
89 of his remaining money
818 of his money =
89 of his remaining money
Amount that Liam spent on the shirt = 9 u
9 u = 45
1 u = 45 ÷ 9 = 5
Amount that Liam had at first
= 18 u
= 18 x 5
= $90
Answer(s): $90
