Introduction

When making a purchase, it's essential to consider the total cost, including sales tax. Seth, a resident of a city near the border of two cities with different sales tax rates, is in a dilemma. He wants to buy a new desk but is unsure which store to choose from due to varying sales tax rates. In this article, we will delve into the mathematical concept of comparing sales tax rates and help Seth make an informed decision.

Understanding Sales Tax Rates

Sales tax rates vary across cities and states. The rate is usually expressed as a percentage of the purchase price. For instance, if the sales tax rate is 8%, the total cost of a $100 item would be $108. To calculate the sales tax, we multiply the purchase price by the sales tax rate.

Calculating Sales Tax

Let's consider an example to understand how sales tax is calculated. Suppose Seth wants to buy a desk for $500. The sales tax rate in Store A is 8%, and in Store B is 9%. To calculate the sales tax, we multiply the purchase price by the sales tax rate.

Store A

Purchase price: $500
Sales tax rate: 8%
Sales tax: $500 x 0.08 = $40
Total cost: $500 + $40 = $540

Store B

Purchase price: $500
Sales tax rate: 9%
Sales tax: $500 x 0.09 = $45
Total cost: $500 + $45 = $545

Comparing Total Costs

Now that we have calculated the total cost of the desk from each store, let's compare them.

Store	Purchase Price	Sales Tax Rate	Sales Tax	Total Cost
Store A	$500	8%	$40	$540
Store B	$500	9%	$45	$545

As we can see, the total cost of the desk from Store A is $540, while the total cost from Store B is $545. This means that Seth would save $5 by purchasing the desk from Store A.

Conclusion

In conclusion, comparing sales tax rates is a crucial step in making an informed decision when purchasing an item. By calculating the sales tax and total cost, Seth was able to determine which store offered the best deal. This mathematical approach can be applied to various scenarios, helping individuals make smart financial decisions.
