Question 121548: Can you please help me with this application problem?
The equation V= -3000t + 22,000 describes the value in dollars of a certain model of car after it is t years old. If a car is worth $13,000 substitute 13,000 into the equation to find the age of the car. Show equation and solve.

all you need to do is plug 13,000 in vor v and solve for t.

13,000 = -3000t + 22,000 --> subtract 22,000 from both sides
-9,000 = -300t --> divide both sides by -300
30 = t

so the car is 30 years old.
