The average annual salary of the employees of a company in the year 2005 was $70,000. It increased by the same factor each year, and in 2006 the average annual salary was $82,000. Let y represent the average annual salary, in thousand dollars, after x years since 2005. Which of the following best represents the relationship between x and y? y = 70(1.17)x
y = 82(1.17)x
y = 70(2.2)x
y = 82(2.2)x
