The average rate of change from June to September is calculated by taking the difference in stock prices between these months and dividing by the number of months between them. From June (87) to September (113), the change is $113 - 87 = 26$. There are 3 months between June and September, so the average rate of change is $26 / 3 = 8.67$ dollars per month.
