(b) Evaluate the expression that is found in part (a) for t = 5. What does the result means in this situation?
Answer: (a) The blank space inside the parenthesis is the number of years and the 2nd blank space is the salary: $167.2 thousand.
The last blank space is 2.t + 167.2.
(b) The value for t = 5 is 177.2 thousand.
Step-by-step explanation: The table in (a) is the description of the salaries per year. After 2008, there is an increase of 2000 per year.
Assuming t is in years, the expression for the salaries per year will be:
s = 2.t + 167.2
For part (b), t = 5. Substitute it into the equation, it is:
s = 2.t + 167.2
s = 2.5 + 167.2
s = 177.2
This means that in year 5, the salary will be $ 177.2 thousand.
