Let's define the function relating the salary to the number of years worked at the company.
-
Independent and Dependent Variables:
- The independent variable, \( x \), represents the number of years worked.
- The dependent variable \( H(x) \) represents the salary, because the salary depends on the number of years worked.
-
Function Definition: Autumn's starting salary is $55,000, and she receives a raise of $4,000 every year. We can establish the function as follows:
\[ H(x) = 55000 + 4000x \]
This function indicates that for each year \( x \), her salary increases by $4,000.
-
Calculating Salary for 8 Years: To find \( H(8) \):
\[ H(8) = 55000 + 4000(8) \] \[ H(8) = 55000 + 32000 \] \[ H(8) = 87000 \]
So \( H(8) = 87000 \).
In summary, the function relating the salary to the number of years worked is:
\[ H(x) = 55000 + 4000x \]
And \( H(8) = 87000 \), meaning after 8 years, Autumn's salary will be $87,000.
