Answer:

$16,748

Step-by-step explanation:

we know that

The equation of a exponential decay function is equal to

y=a(1-r)^x

where

y is the value of the car

x is the number of years

a is the initial value

r is the rate of change

In this problem we have

a=\$25,000\\r=12.5\%=12.5/100=0.125

substitute

y=25,000(1-0.125)^x

y=25,000(0.875)^x

For x=3 years

substitute

y=25,000(0.875)^3=\$16,748
