Question

Mr. Sloan said that his car was worth $30,000 when he first purchased it however over the last three years it has decreased in value $5400 what integer represents the average decrease in value per year?

Answer 1

The integer that represents the average decrease in value per year will be 1800.

Explanation:

Suppose, the average decrease in value per year is
`x` dollar.

So, the amount of decrease in three years will be:
`3x` dollar.

Given that, the value of the car is decreased $5400 over the last three years. So, the equation will be......

`3x=5400\\ \\ x=(5400)/(3)=1800`

Thus, the integer that represents the average decrease in value per year will be 1800.
