A particular rat given n trials in a maze can run through the maze in t minutes, where t=6+20/n+2. How many trials are needed so that the rat can runthrough the maze in exactly eight minutes?

ambiguous equation. Did you mean t = 6 + 20/(n+2) or t = 6 + 20/n + 2 , the way you typed it or t = (6+2)/n + 2 or t = (6+20)/(n+2) each would give you a different result.

Reiny the problem is t=6+20 over n=+2
