A biologist is recording the loss of fish in a pond. He notes the number of fish, f, in the pond on June 1. On July 1 there were 63 fish in the pond, which is 52 fewer fish than were in the pond on June 1.

Which equation represents this situation?

Question 2 options:

63 – f = 52

f + 63 = –52

f – 52 = 63

f + 63 = 52
