Answer: C) Krista takes 25 pictures per day. The initial number of pictures is 55
Step-by-step explanation: In the question, it says she takes 25 pictures per day on a 5-day trip and ends up with 180 pictures. 25 times 5 equals 125 (25*5=125) and she has 180 photos in total, so we must subtract 180 and 125 (180-125=55)
Hope this helps
