Answer:
V(x) = -1600x + 21,000
x (number of years)
Explanation:
"advised "
(a). if x = 4 (replace x with 4)
Using the formula above
V(4) = -1600(4) + 21,000
= -6400 + 21,000
= $14600
Value of the car after four years is $14600.
(b). if x = 8 (replace x with 8)
Using the formula
V(8) = -1600(8) + 21000
= -12800 + 21000
= $8200.
Value of the car after eight years is $8200.
(c). V(10) = 5000
This is the value of the car after 10 years
Check.
V(10) = -1600(10) + 21,000
= -16000+21,000
= $5000.
Value of the car after 10 years is $5000.
