Robin wants to find out the number of salamanders by a pond near her house. She catches 45 of them, puts a leg band on each salamander, and puts them back by the pond. The next week, she catches 50 salamanders. Of those 50 salamanders, 3 have a leg band. Using this information, what is a reasonable estimate of the number of salamanders by the pond?

Given:
1st week: caught 45 salamanders and put leg bands on them
2nd week: caught 50 salamanders and 3 have leg bands

3/50 = 0.06 of the salamander population have leg bands.

45 / 0.06 = 750 total number of salamanders 

45/750 = 0.06 or 6% 

The reasonable estimate of the number of salamanders by the pond is 750 salamanders.
