Harry spent $18 on a jumpsuit. He spent
19 of his remaining money on a sweater. If he still had
49 of his money left, how much did he have at first?
| Jumpsuit |

| $18 |
1 |
8 |
| 5x2 |
4x2 |
| 9 u |
1 u |
8 u |
The amount that Harry 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 Harry spent on the jumpsuit = 9 u
9 u = 18
1 u = 18 ÷ 9 = 2
Amount that Harry had at first
= 18 u
= 18 x 2
= $36
Answer(s): $36
