    This is the way I do it. Often I just divide by ten and multiply by two, but I’m a generous tipper, and it’s one less head math step.

    The funny thing is that this basically how common core math works: get to the answer by doing as much easy math as possible.

      Another method: tax is often about 8%, so double that as a baseline and adjust from there.
