Solution:

Let x, the original price. Now, according to the problem, consider the following diagram:

This diagram is equivalent to:

By cross-multiplication, we obtain:


x\text{ (85\%) = (26.35)(100\%)}

solving for x, we get:


x\text{ =}\frac{\text{ (26.35)(100\%)}}{85\%}=31

So that, we can conclude that the correct answer is:

The original price is $31
