Write a real-life problem situation that could be represented by the equation Y=65x. State what x, y, and 65 represent in your problem and explain how you know the problem represents a proportional relationship.

You have an hour glass that actually takes 65 minutes to finish draining. Give an equation for the number of minutes Y elapse after the timer has expired and been immediately turned over x times.

The graph of the equation is a straight line so the relationship is proportional.
