# How do you find sales tax?

Oct 4, 2017

The explanation is provided for all is the following!

#### Explanation:

Lets start off with the definition. What even is sales tax?:
Sales tax is the "fee" we pay on something purchased. The amount of fee paid always depends on a percentage. An 8% sales tax means that for every 1$, (also 100¢) we spend an extra 8 cents. Before I confuse you too much, I'll just give an example so you won't be like, Whu? What is she talking about?. Example: Part 1 A jacket costs$40 and your state's sales tax (it may vary for each state) is 8%. How much do you have to pay along with your sales tax? There are a few other methods, but in this explanation, I'm just gonna show you this one.

Step 1: Change 8% to a decimal.
8%= 8/100*

*: You can do $0.08$, too!

Step 2: Multiply $0.08$ and and $40$.

$40 \times \frac{8}{100}$

$= 3.2$

So the tax will be $3.20. -----------------------------------But WAIT!!!---------------------------------------------- There's still Part 2 left! You just know the extra amount you are gonna have to pay along with the$40. Once Part 2 is over, we'll have our answer.

Part 2

We now have to add the cost of the jacket ($40) with the tax for us to get the total amount that is due. $40+$3.20 =$43.20

I hope that helps!

Refer to the explanation.

#### Explanation:

Following the previous example of $40.00 and 8%sales tax: 8%=8/100=0.08 Sales Tax $40.00xx0.08=$3.20 Add the sales tax to the original $40.00.

$40.00+$3.20=43.20

You can answer this question with one step.

$40+($40xx0.08)=$43.20 $\textcolor{w h i t e}{\ldots \ldots \ldots \ldots \ldots .} \downarrow$$\textcolor{w h i t e}{\ldots \ldots \ldots . .} \text{sales tax}\$
