Answer:
C
Step-by-step explanation:
You take Photographer B's hours and subtract them. 110-80=30. You know that there is an hour between so you can split 30 in half to get 15. Now that you know Photographer B is charging 15 an hour you can take 80 and subtract 15 twice because it cost 80 at 2 hours. You subtract 30 from 80 and you get 50.
