C)18.75 minutes; 25 haircuts

Step-by-step explanation:

5 hours = 5 * 60 minutes = 300 minutes

5 hours for 16 haircuts =

= 300 minutes: 16 haircuts

= 300/16 minutes : 16/16 haircuts

= 18.75 minutes : 1 haircut

8 hours = 8 * 60 minutes = 480 minutes

480/18.75 = 25.6

18.75 * 25.6 minutes : 1 * 25.6 haircuts

480 minutes : 25.6 haircuts

Since 0.6 haircut is not a full haircut, he can give 25 haircuts in 480 minutes.
