Answer:
Annual increase in price=3.3%
Step-by-step explanation:
Using the cumulative average growth formula, we can compute the average annual increase as follows;
Average annual increase =( Recent price/Initial price)^1/(n-1)
Initial price =$27,358. 8
Recent price = $21,808
n=8
Average annual increase= (27,358. 8/21,808)^(1/(8-1))=3.3%
Annual increase in price
