We have been given the equation
[tex]y=20646(0.86)^x[/tex]
This equation represents the value of the brand car x years after it was purchased.
We have to find the value of the Milo's car 11 years after he purchased. In order to find the same we can substitute x = 11 in the above equation.
On substituting x = 11 in the above equation, we get
[tex]y(11)=20646(0.86)^{11}\\y(11)\approx 3929
[/tex]
Therefore, the value of the car 11 years after purchasing is given by $3929
A is the correct option.
