    Question 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 T = 20.51 - 18.99

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