hi..if you round up the answer will be $80.80.
6.25% sales tax is equivalent to 474.75
in multiplication you have to move the decimal point 4 spaces from the left. if you move the decimal point here...you'll have to move it 2 additional spaces from the left. you end up with 4.75 rounding up. round up again to 5 bucks. add the 5 bucks to 75.80 you get 80.80
