Answer: 951
====================================================
Work Shown:
3/10 = 0.3
3 & 3/10 = 3 + 3/10 = 3 + 0.3 = 3.3
(3 & 3/10) % = 3.3%
3.3% = 3.3/100 = 0.033
3.3% of 921 = 0.033*921 = 30.393 which rounds to 30.39
The amount of tax is $30.39, which adds onto the price $921 to get
921+30.39 = 951.39
Round this to the nearest dollar to get 951
-------------
A slight shortcut
3.3% + 100% = 0.033 + 1.000 = 1.033
Multiply 1.033 with 921 to get 1.033*921 = 951.393 which rounds to 951
Note that 951 is closer to 951.93, even though it's always a good idea to round up to make sure you clear the hurdle. For the sake of this problem, we'll just stick to 951.
