Question

The equation V = -2000t + 23,000 describes the value in dollars of a certain model of car after it is t years old. If a car is worth $15,000, substitute 15,000 into the equation to find the age of the car.

Answer 1

Answer:

The care is 4 years old

Step-by-step explanation:

V = -2000t + 23,000

15000 = -2000t + 23,000

15000 - 23000= -2000t (+ 23,000 - 23000)

- 8000 = -2000t

- 8000/-2000 = -2000t/-2000

t = 4
