Suppose you are helping scientists conduct a study of a population of Rainbow Trout, which is a fish species that lives in California lakes. The scientists initially capture 50 Rainbow Trout from a lake and tag all of them. After 30 days, they capture 75 Rainbow Trout and count 15 tags.

Find the estimated total number of Rainbow Trout in the lake.
__________ Rainbow Trout.

(Hint: Use the equation: N = (M x T)/R)
