You can put this solution on YOUR website! You need to purchase a textbook for nursing school that costs $80.00. The sales tax on the book is 8.25%. You have $100. How much change will you receive back.
-------------
Cost of the book is 80 dollars + 0.0825*80 dollars
= 80 + 6.6 = 86.60 dollars
----------------
Amount of change, if you have $100, is 100-86.60 = $13.40
