Thanks! Can you help with:


This morning, Elena wrote a check in the amount of $42.50. This brought her balance down to –$14.25. Suppose n represents Elena's balance before she wrote the check.



Which equation can be used to represent this situation?



n – 14.25 = –42.50



n – 14.25 = 42.50



n + 42.50 = –14.25



n – 42.50 = –14.25

Question 2






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?




f + 63 = –52



63 – f = 52



f + 63 = 52



f – 52 = 63
