Answers

Answer 1

Answer:

Answer:

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

Step-by-step 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......

$3x=5400\n \n x=(5400)/(3)=1800$

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