Sagot :

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)

[tex]21(0.075)=1.575[/tex]

Then, we add that number to 21.

[tex]21+1.575=22.575[/tex]

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