The percent markup is 11.11 %
Solution:
Given that, the store buys 100 shirts at a cost of $ 2700
Let us find the cost of 1 shirt
[tex]\text{cost of 1 shirt } = \frac{2700}{100} = 27[/tex]
The store sells them at $ 30 each
Therefore,
Cost price of 1 shirt = $ 27
Selling price of 1 shirt = $ 30
Markup price = Selling price - Cost price
Markup price = 30 - 27
Markup price = 3
Thus markup price is $ 3
The percent markup is given as:
[tex]\text{Percent markup } = \dfrac{\text{Mark up}}{\text{Cost price}}\times100\\\\\text{Percent markup } = \frac{3}{27} \times 100\\\\\text{Percent markup } = 11.11[/tex]
Thus the percent markup is 11.11 %
