so what's the first step?

anonymous · Answer

first thing you do (let's do this the quick and short way, my favorite) what is 15% as a decimal? 
as a decimal, 15% is .15 

so to find out what 15% of 120.75 is, do use the equation

0.15 * 120.75 = x

x = the amount you will tip him

$12

$18

$24 These are the answers im not sure about the steps though thats all the question asked lol

anonymous · Answer

so x = 18.113

that's closet to 18 so you will tip the waiter $18

I do it opposite way, but get same answer. I take the amount of the bill, let's say it is 120.75, enter 120.75 x 15% on your calculator. There is a percentage button on it.
