Heather is buying a T-Shirt for $8. Sales tax is 8 1/4 cents per dollar. How much will Heather pay in sales tax on her purchase?

The easiest way to solve this problem is to change the fraction to a decimal. 8 1/4 cents = $0.0825.

Then multiply: 8 * 0.0825 = 0.66

Add: $8.00 + 0.66 = Total cost of shirt

To find out how much Heather will pay in sales tax on her purchase, you need to calculate the sales tax amount based on the total cost of the T-shirt.

First, convert the sales tax rate from a fraction to a decimal. 8 1/4 cents can be expressed as 8.25 cents per dollar. To convert it to a decimal, divide 8.25 by 100, which equals 0.0825.

Next, multiply the total cost of the T-shirt by the sales tax rate in decimal form. Since Heather is buying the T-shirt for $8, the calculation will be:

Sales Tax = 0.0825 * $8

Multiply the decimal value of the tax rate by the total cost:

Sales Tax = 0.0825 * $8 = $0.66

Therefore, Heather will pay $0.66 in sales tax on her purchase.

To calculate the sales tax on Heather's purchase, we'll need to find 8 1/4 cents per dollar and then multiply it by the price of the T-Shirt.

Step 1: Convert 8 1/4 cents to decimal form.
8 1/4 cents can be written as 0.0825 dollars. To convert cents to dollars, we divide by 100 since there are 100 cents in a dollar. So, 8 1/4 cents is equal to 0.0825 dollars.

Step 2: Calculate the sales tax amount.
To find the sales tax amount, we multiply the price of the T-Shirt by the sales tax rate. The price of the T-Shirt is $8, and the sales tax rate is 0.0825 dollars per dollar, so

Sales tax = $8 * 0.0825
= $0.66

Therefore, Heather will pay $0.66 in sales tax on her purchase.
