Charlie spent $45 on a skirt. He spent
15 of his remaining money on a blouse. If he still had
25 of his money left, how much did he have at first?
| Skirt |
Remaining amount |
| |
Blouse |
Left |
| $45 |
1 |
4 |
| 3x2 |
2x2 |
| 5 u |
1 u |
4 u |
The amount that Charlie had left is the same. Make the numerators the same. LCM of 2 and 4 is 4.
2x25x2 of his money =
45 of his remaining money
410 of his money =
45 of his remaining money
Amount that Charlie spent on the skirt = 5 u
5 u = 45
1 u = 45 ÷ 5 = 9
Amount that Charlie had at first
= 10 u
= 10 x 9
= $90
Answer(s): $90
