Tip Question

In my ASVAB prep course, I devote time to teach about how to calculate tip.  Calculating tip is a type of percentage question.  As an ASVAB tutor, I realize that tip is a type of question that can appear on the Arithmetic Reasoning section of the ASVAB.  Tip, sales tax, and commission are solved by using percentages.  Being sure to know how to work with percentages is a key part in improving your ASVAB math score. Do you know how to solve this problem? What do you think the answer is?  The answer and explanation will be posted tomorrow.
