The value of a certain new car (time = 0 years old) is $14,000. After two years (t=2), the value of the car is $9,000.
A. Find the linear equation representing the car after t years.
B. What is the value of the car after 5 years?
Value = 14,000 + k t
k = (9000-14000)/2 = $-2500/year
so
V = 14,000 -2500 t
when t = 5
V = 14,000 - 12,500 = 1,500
