I decided to do Microsoft because it is one the worlds most successful companies. Calculating the average rate of change is finding the difference between cost A and cost B divided by the time span. From Feb 1 – March 3 there is $0.67 difference which is a 1.05% increase. I then divided by 30 days and it equals to $0.02. The company loses $0.02 per day, in the last 30 days. What else do you want to know about the average rate of change.
