    Okay. So she wants to buy a notebook with 7% sales tax. To find the total price, do 4.50 * 107% (1.07). Doing that includes the price + sales tax. When you do that, you get 4.815 or 4.82 when rounded to the nearest hundredth. Jana has enough money to buy the notebook she wants with a $5 bill. She will have 18 cents leftover after the purchase.
