Thread: How do I set up this problem?

Jimmy bought a CD that cost $18.99 and paid $20.51, including sales tax. What is the rate of the sales tax?

Sales tax would be $\displaystyle T = 20.51 - 18.99$

As a percentage on the sale, it would be $\displaystyle P = \frac{T}{Item}$ where Item is the CD that Jimmy bought.
