rewrite this passage in simple terms: As for the job of installing the irrigation system, Waterways would likely choose a different cost driver. This is because the installation process is likely to be more labor-intensive than machine-intensive. In this case, direct labor hours or labor cost might be a more appropriate cost driver. This is because the cost of labor (including wages and benefits) would likely constitute a significant portion of the total cost of the installation job. Therefore, using labor hours or labor cost as the cost driver would allow Waterways to more accurately allocate overhead costs based on the actual resources consumed in the installation process
