Lucy wants to buy a basketball that costs $30. She lives in a state that has 10% sales tax. What is the final price she will pay for the basketball including tax?

To solve anything for tax, you can do it in one step, or 2 steps. To solve it in one step, simply put the tax amount into a decimal, with a one in front. So for this question, you would put 1.10 and multiply by the amount. So 30x1.10=$33. Or you can just multiply 30 by a decimal with a 0. So 0.10x30=3. Then add the 3 to 30

The answer to your question is 1/9
