You just purchased a new I phone for $650. Apple chooses to depreciate the phone using the straight-line method over 5 years. When will the book value of the
phone be $195?

Solve the problem by making up an equation. a man could arrive on time for an appointment if he drove the car at 40 mph; however, since he left the house 15 minutes late, he drove the car at 50 mph and arrive 3 minutes early for the appointment. how far from his house was his appointment?
