Solving equations or inequalities involving solving for the unknown.
If I need to know how much I'll be saving off the retail price using a coupon that gives 30% off for any item, then this is solving an equality.
If I need to know the minimum mark I need on my 4th test to pass a course, then this involves solving an inequality.
The purpose is to make the unknown known.

any time where you would want to know how much money you would have to make to break even, or any similar situation. when will it be worth it to do one thing instead of another, etc.
i like my calculus professor's example about how math could save your life. a man puts a gun to your head one day and says "find the zeros in this equasion or i'll kill you!"
