Answer:
100%
Step-by-step explanation:
The markup of the item is the difference between the sale price and the cost:
2 - 1 = 1 . . . . markup of 1 on cost of 1
The percentage markup is the ratio of markup to cost, converted to a percentage:
markup/cost × 100% = 1/1 × 100% = 100%
The boutique's markup percentage is 100%.
