To calculate the sales tax rate, you can use the following formula:
Sales Tax Rate = (Sales Tax / Cost of Item) x 100%
In this case, the cost of the shirt is $3,499, and the sales tax is $210. Plugging these values into the formula gives us:
Sales Tax Rate = ($210 / $3,499) x 100%
Now, performing the calculation:
1. Divide $210 by $3,499, which equals approximately 0.0601.
2. Next, multiply by 100% to convert the decimal to a percentage:
0.0601 x 100% = 6.01%
Therefore, the sales tax rate is approximately 6.01%.
