6Able Construction Company has been awarded a job to remodel the Lvingston's home. As the number of workers on the job increases, the number of hours to complete the remodeling decreases, and this in turn affects the overall cost. A graph representing this situation is shown. What does each axis represent?
- Ax-axis: hours, y-axis: workers
- Bx-axis: hours, y-axis: cost
- Cx-axis: cost, y-axis: workers
- Dx-axis: workers, y-axis: hours
