**Understanding Sales Tax: A Guide to Tony, Juan, and Isabel's Situation**

What is Sales Tax?

Sales tax is a type of consumption tax levied by governments on the sale, transfer, or rental of goods and services. It is typically collected by the seller and remitted to the government. In the United States, sales tax rates vary by state and locality, with some states having no sales tax at all.

The Situation: Tony, Juan, and Isabel

Tony, Juan, and Isabel live in a city where the combined state and local sales tax rate is 8%. They each purchased the same computer and paid $100 in sales tax. This raises an interesting question: how can we determine the cost of the computer and the sales tax rate?

Q&A: Understanding Sales Tax

Q: What is the cost of the computer?

A: To determine the cost of the computer, we need to know the total amount paid by each person, including the sales tax. Let's assume the total amount paid by each person is $108 (computer cost + $100 sales tax). Since the sales tax rate is 8%, we can set up an equation to solve for the cost of the computer:

Computer Cost + (Computer Cost x 0.08) = $108

Simplifying the equation, we get:

Computer Cost + $8.64 = $108

Subtracting $8.64 from both sides, we get:

Computer Cost = $99.36

So, the cost of the computer is $99.36.

Q: What is the sales tax rate?

A: We already know the sales tax rate is 8%. However, we can also calculate it using the cost of the computer and the sales tax paid. Let's use the cost of the computer we calculated earlier ($99.36) and the sales tax paid ($100):

Sales Tax Rate = (Sales Tax Paid / Computer Cost) x 100

Plugging in the values, we get:

Sales Tax Rate = ($100 / $99.36) x 100 ≈ 10.06%

However, this is not the combined state and local sales tax rate, which is 8%. This means that the sales tax rate we calculated is not the actual rate, but rather the rate that would be applied if the sales tax were calculated on the cost of the computer alone.

Q: How can we determine the actual sales tax rate?

A: To determine the actual sales tax rate, we need to know the total amount paid by each person, including the sales tax. Let's assume the total amount paid by each person is $108 (computer cost + $100 sales tax). We can set up an equation to solve for the sales tax rate:

Total Amount Paid = Computer Cost + (Computer Cost x Sales Tax Rate)

Simplifying the equation, we get:

$108 = $99.36 + ($99.36 x Sales Tax Rate)

Subtracting $99.36 from both sides, we get:

$8.64 = $99.36 x Sales Tax Rate

Dividing both sides by $99.36, we get:

Sales Tax Rate = $8.64 / $99.36 ≈ 0.087

Converting this to a percentage, we get:

Sales Tax Rate ≈ 8.7%

This is close to the combined state and local sales tax rate of 8%. However, it's not exactly the same, which means that the sales tax rate we calculated is not the actual rate, but rather the rate that would be applied if the sales tax were calculated on the cost of the computer alone.

Q: What is the difference between the calculated sales tax rate and the actual sales tax rate?

A: The difference between the calculated sales tax rate and the actual sales tax rate is due to the fact that the sales tax rate is applied to the total amount paid, not just the cost of the computer. In this case, the calculated sales tax rate is 8.7%, while the actual sales tax rate is 8%. This means that the sales tax rate is being applied to a smaller amount (the cost of the computer) than the actual amount paid (the total amount paid).

Q: What does this mean for Tony, Juan, and Isabel?

A: This means that Tony, Juan, and Isabel are paying a slightly higher sales tax rate than the combined state and local sales tax rate of 8%. This is because the sales tax rate is being applied to the cost of the computer alone, rather than the total amount paid.

Q: How can we avoid paying a higher sales tax rate?

A: To avoid paying a higher sales tax rate, Tony, Juan, and Isabel should make sure to pay the correct amount of sales tax. This can be done by checking the sales tax rate and the cost of the computer before making a purchase. They should also make sure to keep track of the sales tax paid and the total amount paid to ensure that they are not paying a higher sales tax rate than necessary.

Q: What are some other factors that can affect sales tax rates?

A: There are several other factors that can affect sales tax rates, including:

State and local tax laws: Sales tax rates can vary depending on the state and locality where the purchase is made.
Type of goods or services: Some goods or services may be exempt from sales tax, while others may be subject to a higher sales tax rate.
Tax exemptions: Some individuals or businesses may be exempt from paying sales tax, such as non-profit organizations or government agencies.
Tax holidays: Some states or localities may offer tax holidays, which can reduce or eliminate sales tax on certain goods or services.

Q: How can I find out more about sales tax rates in my area?

A: To find out more about sales tax rates in your area, you can:

Check with your local government: Contact your local government or tax authority to find out more about sales tax rates in your area.
