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?

Average decrease in car's value per year = 1800$

Explanation:

  The worth of car bought by Mr. Solan = 30000$

  Reduction of car's price = 5400$

  Number of years considered for measuring reduction of car's price = 3 years.

  Average of values = Total of the values/ Number of values.

  Average reduction per year = Total reduction/ Number of years.

                                                 = 5400/3 = 1800$

  So average decrease in car's value per year = 1800$
