A tire that sells for $40 costs the buyer $43.20 when sales tax is added. What is the percent of sales tax?

$43.20 - $40.00 = $3.20 sales tax
$3.20/$40.00 = 8% sales tax rate ;

To find the percent of sales tax, you need to determine the difference between the sale price and the original price, and then find out what percentage this difference is of the original price.

Find the difference in price due to sales tax:
The tire's original price is $40, and with tax, the total price is $43.20.
e x t S a l es t a x am o u n t = 43.20 − 40.00 = 3.20

Calculate the sales tax rate as a percentage of the original price:
To find the percentage, use the formula:
e x t S a l es t a x p erce n t = ( Original price Sales tax amount ​ ) × 100
Substituting the values:
Sales tax percent = ( 40.00 3.20 ​ ) × 100
Sales tax percent = 0.08 × 100 = 8%
Therefore, the percent of sales tax is 8%.
