You go to a restaurant with a friend. you purchase $8.25 for a meal and $2.20 for a drink. your bill has sales tax of 6%, how much is your bill?

8.25 + 2.20 = 10.45

10.45 * 1.06 = 11.08

or 10.45 * .06 = .627 then round to the hundredth position because it's talking about money and add back to the total of the bill.
10.45 + .63 = 11.08
