It takes about 14 person-hours of labor to break up a driveway and clear away the rubble. It takes about 8 person-hours of labor to pour and smooth concrete for the new driveway.

22 person-hours

Step-by-step explanation:

It takes 14 hours to break up the driveway and then to clear away the rubble.

Then it takes 8 hours to pour the concrete and smooth it.

Total time it will take to break up a driveway, clear away the rubble, pour the concrete, and smooth the concrete will therefore be;

= 14 + 8

= 22 person-hours
