Question

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

Answer 1

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)


`21(0.075)=1.575`

Then, we add that number to 21.


`21+1.575=22.575`

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