Answer 1

The average annual salary of the employees of a company in the year 2005 was $80 thousand. It increased by the same factor each year and in 2006, the average annual salary was $88 thousand. Let f(x) represent the average annual salary, in thousand dollars, after x years since 2005. Which of the following best represents the relationship between x and f(x)?

f(x) = 88(0.88)x

f(x) = 88(1.1)x

f(x) = 80(0.88)x

f(x) = 80(1.1)x

Answer 2

Answer 3
