Oddly, yes.

Percentages also add together in partials. As in 10%+5%+2% = 17%

So, you start with the 10% by moving the decimal over 83.27 becomes 8.327

Then add half of that (5%) to its self and get 12.49 (rounded)

Then take the 10% number and move the decimal over once more (1%) for 0.833 and double it (from 1% to 2%) and get 1.666 and add that to your running total to get your answer of 14.16 (rounding)

And when I calculator check this I got 14.1559.
