What kind of equations have you learned about? Linear, polynomial, exponential? If you give more details, I could help you with a specific type of equation.
What about interest rate and growth on a savings account? That would be an exponential equation based on time (i.e. how often interest is added to the account). Check out this website: http://math2.org/math/general/interest.htm
