Final answer:
To calculate the sale price of an item with sales tax, convert the sales tax rate to a decimal, multiply it by the item's price to find the sales tax amount, and add it to the original price. Round to two decimal places if dealing with currency.
Step-by-step explanation:
Finding the Sale Price with Sales Tax
To find the sale price of an item including sales tax, follow these steps:
- Determine the original price of the item.
- Convert the sales tax rate from a percentage to a decimal by dividing by 100.
- Multiply the original price by the decimal sales tax rate to find the amount of sales tax.
- Add the amount of sales tax to the original price to get the total sale price.
- Round the total sale price to the nearest cent, if necessary, for currency accuracy.
For instance, if an item costs $150.00 and there is a 10% sales tax, first convert 10% to a decimal (0.10) and then multiply by the item's price:
$150.00 x 0.10 = $15.00
Next, add the sales tax to the original price to find the total amount:
$150.00 + $15.00 = $165.00
This is the total amount you would pay, including sales tax.
