Could somebody explain to me?

Question

When you go out to eat, you always tip 20% of the bill amount. But who’s got the time to calculate the right tip amount every time? Not you that’s for sure! You’re making a program to calculate tips and save some time.

Your program needs to take the bill amount as input and output the tip as a float.

Sample Input
50

Sample Output
10.0

Answer 1

It's actually fairly simple. You should write a code that outputs 20% of the entered amount. So you want to take an input, let's say 'b' and return 'b * 0.2', which will be 20% of 'b'

Answer 2

50 * 20/100 = 10.0

Answer 3

Ok thanks
