Answer:
The percent markup is 25%.
Explanation:
Percent markup:
The percent markup is given by the difference in selling price and buying price multiplied by 100% and divided by the buying price.
A department store buys 400 shirts at a cost of $9,600
This means that the buying price is:
$9600/400 = $24
Find the percent markup.
Buying price: $24
Selling price: $30
30 - 24 = 6
6*100%/24 = 25%
The percent markup is 25%.
