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:
[tex]x\text{ (85\%) = (26.35)(100\%)}[/tex]
solving for x, we get:
[tex]x\text{ =}\frac{\text{ (26.35)(100\%)}}{85\%}=31[/tex]
So that, we can conclude that the correct answer is:
The original price is $31
