| Cost price |

100% |
| Profit |

+ 30% |
| Selling price |
|
130% |
Cost price of the vest in percentage = 100%
Cost price of the windbreaker in percentage
= 100% - 40%
= 60%
Selling price of the vest in percentage
= 100% + 30%
= 130%
130% → 39
1% → 39 ÷ 130 = 0.30
60% → 60 x 0.30 = 18
Cost price of the windbreaker = $18
Answer(s): $18
