How do I add a code in so it will put out a Tip Amount on a Bill??

[Jeremy Rohrer]

def main():
    BillAmount = raw_input('Enter the bill amount: ')
    TipAmount = CalcTip(check, total)
    
    print 'The tip on $&.2f is $%.2f.' % (BillAmount, TipAmount)

def CalcTip():
    return 0

#Call main
main()

I just need it to print out the calculation for a 15% tip. This is all I have and I have no idea what else to do. Please Help. Thank You.

The tip is 15% times the bill amount. This is very simple code and so you should figure it out how to mulitply for yourself.

It is simple as dwblas mentioned. Hint:

def CalcTip(bill, tip):
    return bill*tip
