Question
E = 18,000 - 2,000t
V = 18,000(0.85)t
The given equations are two different models that can be used to find the value, in dollars, of a particular car t years after it was purchased. Which of the following statements correctly compares the values of E and V for 0 < t < 9 ?
- E is always less than V.
- E is always greater than V.
- E is initially greater than V but eventually becomes less than V.
- E is initially less than V but eventually becomes greater than V.
The correct answer is: E is initially greater than V but eventually becomes less than V.
