Using linear functions, it is found that both people are paid the same.
A linear function is modeled by:
y = mx + b
In which:
For Bob, we have that that the intercept is of 30000, with a slope of $600, hence his salary after x years is given by:
B(x) = 30,000 + 600x.
For Sue, we have that that the intercept is of 2 x 15000 = 30000, which is the fixed yearly salary with a slope of 2 x 300 = $600, hence her salary after x years is given by:
S(x) = 30,000 + 600x.
The salaries are equal, that is, both people are paid the same.
