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

part/whole = 20%

part/50 = 20/100

part = 50 * (0.2)

part = 10.0

Note:
part is the tip.
whole is the bill amount.
20% is tip percentage.

I hope this helps.
