Question

Roni recently bought a car for $18,000. Her research shows the car will depreciate by an average of $1,500 per year. If x represents the number of years Roni owns the car, which of the following equations represents the value of the car after x years?

A.
y = 18,000x - 1,500
B.
y = 1,500x - 18,000
C.
y = 18,000 + 1,500x
D.
y = 18,000 - 1,500x

Answer 1

D is the answer

Explanation:

If every year the value decreases by $1,500 that variable will change, but the price he bought the car at will not. That is why the x variable(standing for years) would go into the 1,500. And if each year the value decreases the answer would be D

Answer 2

Answer: D. y=18,000 - 1,500x

Step-by-step explanation: the answer is d.) because the cars value will go down as time pas, so 1,500 represent the money and x could represent one year and you subtract it from 18,000 which is the original value of the car.
