a car depreciates in by avalue of $1000 per year. The original value of the car is $30,000. Let V(x) be the value of the car in x years.
Write the linear function that represent the value of the car in x years.
what will be the value of the car after 7 years?

v(x) = 300001000x
v(7) = 300001000(7) = $23000
