SOLUTION: The equation V = -2000t + 20,000 describes the value in dollars of a certain model of car after it is t years old. If a car is worth $14,000, find the age of the car.

Question 1093292: The equation V = -2000t + 20,000 describes the value in dollars of a certain model of car after it is t years old. If a car is worth $14,000, find the age of the car.

This is very easy and it is a must for you to learn. The problem gives you the solution:
V = -2000t+20000
so the problem is telling you that the value of the car decreases -2000 for every t.
The current value of the car is 14000, so:
14000 = -2000t+20000 subtract 20000 on both sides:
-6000 = -2000t divide both sides by -2000, and remember -/- = +
t = 3
