Final answer:

It takes 22 person-hours of labor to break up a driveway, clear the rubble, pour the concrete, and smooth the concrete.

Step-by-step explanation:

To find out how many person-hours of labor it takes to both break up a driveway, clear away the rubble, pour the concrete, and smooth the concrete, we simply add the person-hours required for each task. According to the given information, breaking up a driveway and clearing away the rubble takes about 14 person-hours of labor, and pouring and smoothing concrete takes about 8 person-hours of labor.

The total amount of labor in person-hours required to complete both tasks is calculated as follows:

  1. Breaking up and clearing: 14 person-hours
  2. Pouring and smoothing: 8 person-hours
  3. Total labor: 14 + 8 = 22 person-hours

Therefore, the correct answer is 22 person-hours of labor (Option C).
