The best way to go about this questions is to write out a formula in which x represents the original price of the dress: x*0.90=27. To see where the 0.90 came from, if Kate's dress was 10% off, she must have paid 90% of the original price (100%-10%=90%). Then, to convert a percentage to a decimal, move the decimal point twice to the left so 90% becomes 0.90. Then, our formula essentially means that 90% of some number (x) is equal to 27. To solve for x, divide both sides of the formula by 0.90 to get x=$30 which is the final answer.

I hope this helps.

The original price of the dress is $30.

Given that, Kate paid $27 for a dress that was on sale for 10% off.

We need to find what was the original price of this dress.

How is math used in sales?

Retail math is used daily in various ways by store owners, managers, retail buyers, and other retail employees to evaluate inventory purchasing plans, analyze sales figures, add-on markup, and apply markdown pricing to plan stock levels in the store.

Let the original price of the dress be x.

Now, x-10% of x=27

⇒x-0.1x=27

⇒0.9x=27

⇒x=30

Therefore, the original price of the dress is $30.
