Kate paid $27 for a dress that was on sale for 10% off. what was the original price of this dress?

Since it was on sale for 10% off, Kate still had to pay 90% of the original price.

Let x be the original price of the dress.
Our equation can be expressed as

27=x*0.90
x=27/0.90
x=30

Therefore the original price of the dress was $30
