The value of a brand new SUV is currently $15,400. After every year, the value of the SUV decreases by 10%.
a)First construct an exponential decay equation:

(A) V = 15400(1 – 10)t

(B) V = 15400(1 – 0.10)t

(C) V = 15400(0.10)t

(D) V = 15400(10 – 0.10)t

b) When will the value of the SUV be $12,465?

t =

(A) 1 year

(B) 2 years

(C) 3 years

(D) 4 years

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
