Question

If a 4 foot piece of rope is cut off one end of a 500 foot rope, in how many days will only 80 feet remain?

Answer 1

500 - 80 = 420 feet

420 divided by 4 = 105

105 days

Answer 2

I am assuming that you meant that a 4ft piece of rope was taken per day.  If that is the case then you have to set up a simple equation to solve.

You have 500 ft rope

You LOSE 4 ft per day

You want to know when it's going to be 80

500 - 4x = 80 where x is the day

Solve for x

500 = 80 + 4x

420 = 4x

105 = x

So it will take 105 days.
