The sales tax for an item was 39.60$ and it cost 440$ before tax. Find the sales tax rate. Write your answer as a percentage.
To find the sales tax rate, we can divide the amount of sales tax by the cost of the item before tax and then multiply by 100 to convert it to a percentage.
The amount of sales tax is $39.60, and the cost of the item before tax is $440.
Sales tax rate = (Amount of sales tax / Cost of item before tax) * 100
Sales tax rate = ($39.60 / $440) * 100
Sales tax rate ≈ 0.09 * 100
Therefore, the sales tax rate is approximately 9%.
