Answer:
b. 2 yrs
Step-by-step explanation:
-Given the initial value at time t=0 as $15,400 and the decay rate as 10%.
-The exponential decay is given by the formula;
We can therefore write our decay expression as;
Hence, our exponential decay equation is
b. Having determined the decay function as , we make $12465 our y value and solve for time, t;
Hence, the value of the car will be $12,465 after 2 years
