For groups of four or more diners, many restaurants add a 15% gratuity and a tax of 8% to the bill. If the bill (including gratuity and tax) for four people came to $193, how much was the tip?

**Anonymous**, Saturday, February 13, 2010 at 12:22amI assume the 8% tax is added first, then the 15% tip.

So, first, add 8% to the bill amount to get a subtotal

subtotal = 193 + 0.08(193)

The same thing can be done more succinctly as follows:

subtotal = 1.08(193)

Then take 15% of that to determine the top:

tip = 0.15(subtotal)

To chain it all together:

tip = 0.15(1.08(193))
