If a dress costs $27.00 when it is on sale for 10% off, what is its original price?

Let x be the original price of the dress.

10% of x will be 0.10x.

So, if the dress is on sale for 10% off, the price will be x - 0.10x = $27.00. Simplifying this gives us:

0.90x = $27.00

Dividing both sides by 0.90 gives us:

x = $30.00

Therefore, the original price of the dress is $30.00.
