Final answer:
To find the original price of the dress, divide the sale price by the percentage of the sale price compared to the original price.
Step-by-step explanation:
To find the original price of the dress, we need to determine the price before the sale. Since the sale price is 70% of the original price, we can set up the equation:
70% of the original price = $18.74
To solve for the original price, we divide both sides of the equation by 70% (which is the same as dividing by 0.70):
Original price = $18.74 ÷ 0.70
Simplifying the division, we get:
Original price = $26.77
