I have one more problem that I need help with. If someone can help me set up the problem I will be able to solve it for my answer. I don't know where to begin with this problem. Thank you for your help it's greatly appreciated.
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?

I 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))
