Answer: $32
Explanation:
We can find the original price by creating a proportion. Let x be the original price of this dress. We will have the cost in the numerator and the percentage as a whole number of the original dress cost in the denominator.
Given:

Cross-multiply:
85 * x = 27.2 * 100
Multiply:
85x = 2,720
Divide both sides of the equation by 85:
x = $32
