What is the total price of a $21 item including 7.5% sales tax? ? plz explain how you get the answer

In order to get the total price, we need to figure out 7.5% of 21, then add that number to 21.

In order to get 7.5% of 21, we just multiply 21 by 0.075 (since 7.5% ind decimal form is 0.075)



Then, we add that number to 21.



The answer is 22.575, which we can round to $22.58.
