If x represents the number of years, then Having x=11, you simply substitute in the given equation, being 20646*(0.86*11)=$195311.16
One question, brother: Did you copy well the equation or should it be 20646-0.86x?
Because if this is the case, the answer would be D
20646-(0.86*11)=20636.54 or roughly $20637
