Mathematics

$x=\$0.8325$

Step-by-step explanation:

We need to analize the exercise.

We know that the sales-tax rate in your state is 4.5% and the cost of the CD is $18.50.

Then, let be "x" the the amount of sales tax you will pay for the CD.

You can write this expression:

$x=(\$18.50)(\frac{4.5}{100})$

Evaluating, you get that the value of "x" is:

$x=\$0.8325$
