How to create an if statement program to calculate a tip?

Question:

I’m trying to write a program for my homework:

Write a program to determine how much to tip the server in a restaurant. The tip should be 15% of the check, with a minimum of $2.

The hint said to use an if statement, but i keep running into a alot of errors.

I don’t know how else to write it, I’ve been trying to figure it out for a couple of hours now and haven’t found proper answers online…

Check = 59
Tip = (Check)*(0.15)

if Tip > 2: 
    print(Tip)

Answers:

It means you first use if statement to see if the check is more than 2 before you do the math

check = 59
if check > 2:
    tip = check * 0.15
    print(tip)

Output:

8.85

It’s not clear whether only checks larger than $2 get tips, or whether tips must be at least $2.

I’m guessing the former, because you can do that with an if statement:

check = 59
if check > 2:
    tip = 0.15*check

Or more compactly, like this:

tip = check*0.15 if check > 2 else 0

Whereas if the intent is that the tip must be at least $2, an if statement isn’t really necessary:

check = 59
tip = max(2, 0.15*check)

But if you HAD to use an if statement (though max is more elegant), you could do it like this:

check = 59
tip = 0.15*check
if tip <= 2:
    tip = 2

But this is quite inelegant.

First initialise your variable tip = 2 then if the tip percentage of 15% is higher apply the tip percentage to your variable tip:

check = 30

tip = 2
tip_perc = check * 0.15

if tip_perc > 2:
    tip = tip_perc

print(tip)
