We are given that Tracey paid $185 for an item that costs $360. To determine the percentage of the original price she paid we will use the following relationship:

Where "x" is the percentage of 360 that yields 185. Now we solve for "x" first by multiplying both sides by 100:

Now we divide both sides by 360:

Solving the operation:

Therefore, Tracey paid 51.39 percent of the original price.
