Julian had $138 more than Jack. After each of them bought a different cardigan from a shop. Julian and Jack were left with equal amount of money. Given that Julian's cardigan cost 4 times as much as Jack's cardigan, how much did Julian's cardigan cost?

Before |
1 u + 4 p |
1 u + 1 p |
$138 |
Change |
- 4 p |
- 1 p |
|

1 u |
1 u |

The amount that Julian and Jack had in the end is the same.
4 p - 1 p = 138
3 p = 138
1 p = 138 ÷ 3 = 46
Cost of Julian's cardigan
= 4 p
= 4 x 46
= $184
Answer(s): $184
