+# [Boiled Eggs](https://www.codewars.com/kata/boiled-eggs "https://www.codewars.com/kata/52b5247074ea613a09000164")
+
+You are the greatest chef on earth. No one boils eggs like you! Your restaurant is always full of guests, who love your boiled eggs. But
+when there is a greater order of boiled eggs, you need some time, because you have only one pot for your job. How much time do you need?
+
+## Your Task
+
+Implement a function, which takes a non-negative integer, representing the number of eggs to boil. It must return the time in minutes (
+integer), which it takes to have all the eggs boiled.
+
+## Rules
+
+* you can put at most 8 eggs into the pot at once
+* it takes 5 minutes to boil an egg
+* we assume, that the water is boiling all the time (no time to heat up)
+* for simplicity, we also don't consider the time it takes to put eggs into the pot or get them out of it
+
+## Example (Input --> Output)
+
+```
+0 --> 0
+5 --> 5
+10 --> 10
+```
