To find the sales tax percentage, we follow these steps:
Step 1: Determine the amount of sales tax paid.
This is the difference between the final price and the price before tax.
So, tax paid = final price - price before tax
= $68.20 - $62
= $6.20
Step 2: Calculate the sales tax percentage.
The sales tax percentage is the amount of tax paid divided by the price before tax, then multiplied by 100 to convert it to a percentage.
Tax percentage = (tax paid / price before tax) * 100
= ($6.20 / $62) * 100
= 0.1 * 100
= 10%
Thus, the sales tax percentage is 10%.
