you want to buy a shirt that costs $20. The sales tax is 7.25%.What is the total cost of the shirt?

To calculate the total cost of the shirt, we need to add the sales tax to the original price.

Sales tax is calculated by multiplying the original price by the sales tax rate (expressed as a decimal).

Sales tax = Original price × Sales tax rate

In this case, the original price of the shirt is $20, and the sales tax rate is 7.25% or 0.0725.

Sales tax = $20 × 0.0725

Sales tax = $1.45

Now, to find the total cost of the shirt, we add the sales tax to the original price.

Total cost of the shirt = Original price + Sales tax

Total cost of the shirt = $20 + $1.45

Total cost of the shirt = $21.45

Therefore, the total cost of the shirt, including sales tax, is $21.45.

To find the total cost of the shirt including sales tax, you need to calculate the amount of tax and add it to the original price. Here's how you can do it:

Step 1: Calculate the tax amount
Multiply the price of the shirt by the sales tax rate as a decimal. In this case, the sales tax rate is 7.25%, or 0.0725 as a decimal.
Tax amount = $20 × 0.0725

Step 2: Add the tax amount to the original price to get the total cost.
Total cost = $20 + tax amount

Now let's calculate the tax amount and total cost:

Tax amount = $20 × 0.0725
= $1.45 (rounded to two decimal places)

Total cost = $20 + $1.45
= $21.45

Therefore, the total cost of the shirt, including sales tax, is $21.45.

0.0725 * 20 = 1.45

20.00 + 1.45 = ?
