a)

The initial value of the car is $19,000, and after each year after 2012, the value decreases by $600.

So, the value V after t years will be 19000 minus t times 600, therefore the corresponding equation is:


V(t)=19000-600t

b)

In 2018, we have 6 years after 2012, so t = 6.

Calculating the value of V for t = 6, we have:


\begin{gathered} V(6)=19000-600\cdot6 \\ V(6)=19000-3600 \\ V(6)=15400 \end{gathered}

Therefore the value of the car in 2018 is $15,400.
