Phineas and Ferb are trying to build the world's tallest water slide. They build the slide in sections that are each 666 meters tall. They want it to be 5 meters taller than the next tallest slide, which is 49 meters tall.

Let n stand for the total number of sections Phineas and Ferb need to achieve their goal. Choose the best equation to represent this problem:

a: (49+5)6=n

b: (49+5)/6=n

c: (49-5)/6=n
