A store owner buys brooms for $4 and sells them at a markup of 270%. One day, she decides to put them on sale and marks them down by 25%.
What is the sale price of a broom?
To calculate the sale price of a broom, we need to find the selling price after the 25% markdown.
First, let's find the selling price before the markdown. The store owner sells the brooms at a markup of 270%. This means the selling price is 270% of the buying price or 100% + 270% = 370%.
So, the selling price before the markdown is $4 * 370% = $<<4*370*.01=14.8>>14.8.
Next, let's calculate the amount of the markdown. The markdown is 25% of $14.8, which is $14.8 * 25% = $<<14.8*25*.01=3.7>>3.7.
Finally, we can calculate the sale price by subtracting the markdown from the selling price before the markdown: $14.8 - $3.7 = $<<14.8-3.7=11.1>>11.1.
Therefore, the sale price of a broom is $11.1.
