John spent $50 on a blouse. He spent
15 of his remaining money on a jumpsuit. If he still had
25 of his money left, how much did he have at first?
| Blouse |
Remaining amount |
| |
Jumpsuit |
Left |
| $50 |
1 |
4 |
| 3x2 |
2x2 |
| 5 u |
1 u |
4 u |
The amount that John 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 John spent on the blouse = 5 u
5 u = 50
1 u = 50 ÷ 5 = 10
Amount that John had at first
= 10 u
= 10 x 10
= $100
Answer(s): $100
