Final answer:
To find the sales tax rate, subtract the price of the item from the total amount paid. Divide the amount of sales tax by the price of the item and multiply by 100% to get the sales tax rate.
Step-by-step explanation:
To find the sales tax rate, we need to determine the difference between the price of the item and the total amount paid. In this case, the price of the item is $35 and the total amount paid is $38.22.
So, the amount of sales tax paid is $38.22 - $35 = $3.22.
To find the sales tax rate, divide the amount of sales tax by the price of the item and multiply by 100%:
Sales tax rate = ($3.22 / $35) x 100% = 9.2% (rounded to one decimal place).
