Suppose the output of a factory (output) and the number of workers (workers) is represented by a linear function output $$=a+b$$ workers, where $$a$$ and $$b$$ are constants. You know that when there are 5 workers, the output is 15 . When there are 10 workers, the output is 20. Solve for the constant $$a$$ Solve for the constant $$b$$ If there are 20 workers, what is the output expected to be? If the factory hires 6 more workers, what is the expected increase in output?
