5635.19 dollars (approx)

Step-by-step explanation:

Since, the initial value of car is 16400 dollars,

And, it is decreasing per year by the rate of 12.5%

Thus, the new price of car after x years,

$f(x) = 16400(1-\frac{12.5}{100} )^x$

f(x) = 16400(1-0.125 )^x

f(x) = 16400(0.875 )^x

For x = 8 years,

f(8) = 16400(0.875 )^8

$f(8) = 16400\times 0.343608915806$

$f(8) = 5635.18621922\approx 5635.19$

Therefore, the price of car after 8 years is 5635.19 dollars(approx)
