Quick tip about 20% tips.
Move the decimal over 1 place to the left and multiply by 2.
For this equation it would look like this:
18.37 ---> 1.837
(1.837)(2) = 3.674
So, if we rounded to the nearest dollar like the question is asking then we round to $4.
Another way to do this is to multiply 18.37 by .20:
(18.37)(.20) = 3.674
Either way it is $4.
