Luis purchases a refrigerator for $500 in iowa, where the sales tax rate is 6.5%. what is the amount of sales tax?

To find sales tax, we use the given rate (6.5%) and convert it to a decimal so .065. We multiply the tax rate by the price of the product, $500. 
.065 * 500 = 32.5
That is your $32.50. 

Hope this helps. :) Please consider giving brainliest answer and a thanks to answers you find most helpful.
