Answer:

The value of the car after 10 years will be $32669.74

Step-by-step explanation:

The value of the car was $38,000 in 2007. Its value depreciated by 1.5% every year.

To find its value after T years, we use the formula of compound interest (with decreasing rate):

[tex]A = P(1 - R)^T[/tex]

where A = value after T years

P = Principal (initial value of car)

R = rate of decrease of value = 1.5% = 0.015

Therefore, the value of the car after 10 years (2017) is:

[tex]A = 38000(1 - 0.015)^{10}\\\\A = 38000(0.985)^{10}\\\\A = 38000 * 0.85973\\\\[/tex]

=> A = $32669.74

The value of the car after 10 years will be $32669.74.

Based on the amount the car is depreciating by and its value in 2007, in 2017, the car would be worth $32,669.76.

The worth of the car can be calculated using the future value formula:

= Amount x ( 1 + rate) ^ number of years

As the value is decreasing, the rate will be negative.

The number of years is:

= 2017 - 2007

= 10 years

Solving would give:

= 38,000 x (1 - 1.5%) ¹⁰

= $32,669.76

In conclusion, the car would be valued at $32,669.76 in 2017.
