Introduction

When shopping, it's essential to consider the total cost of items, including tax. In this article, we will explore how to calculate the total cost of items with tax, using a real-world example. We will use a state sales tax of 7 percent and calculate the total cost of four items: a water bottle, a flashlight, a toothbrush, and a compass.

Understanding Sales Tax

Sales tax is a type of consumption tax levied by governments on the sale of goods and services. It's usually a percentage of the purchase price of an item. In our example, the state sales tax is 7 percent. This means that for every dollar spent, 7 cents will go towards sales tax.

Calculating Sales Tax

To calculate sales tax, we multiply the price of an item by the sales tax rate. For example, if an item costs $10 and the sales tax rate is 7 percent, the sales tax would be:

$10 x 0.07 = $0.70

This means that the total cost of the item, including tax, would be:

$10 + $0.70 = $10.70

Calculating the Total Cost of Items

Now that we understand how to calculate sales tax, let's calculate the total cost of our four items: a water bottle, a flashlight, a toothbrush, and a compass.

Water Bottle

The price of the water bottle is $1.50. To calculate the sales tax, we multiply the price by the sales tax rate:

$1.50 x 0.07 = $0.105

Rounding to two decimal places, the sales tax is $0.11. The total cost of the water bottle, including tax, is:

$1.50 + $0.11 = $1.61

Flashlight

The price of the flashlight is $2.99. To calculate the sales tax, we multiply the price by the sales tax rate:

$2.99 x 0.07 = $0.2093

Rounding to two decimal places, the sales tax is $0.21. The total cost of the flashlight, including tax, is:

$2.99 + $0.21 = $3.20

Toothbrush

The price of the toothbrush is $1.29. To calculate the sales tax, we multiply the price by the sales tax rate:

$1.29 x 0.07 = $0.0903

Rounding to two decimal places, the sales tax is $0.09. The total cost of the toothbrush, including tax, is:

$1.29 + $0.09 = $1.38

Compass

The price of the compass is $3.29. To calculate the sales tax, we multiply the price by the sales tax rate:

$3.29 x 0.07 = $0.2293

Rounding to two decimal places, the sales tax is $0.23. The total cost of the compass, including tax, is:

$3.29 + $0.23 = $3.52

Calculating the Total Cost of All Items

Now that we have calculated the total cost of each item, including tax, let's calculate the total cost of all items.

$1.61 + $3.20 + $1.38 + $3.52 = $10.71
