1960 to 1970 ... 100(.06-.04)/.04 = 50%
1970 to 1980 ... 100(.15-.06)/.06 = 150%
1980 to 1990 ... 100(.25-.15)/.15 = 67%
1990 to 2000 ... 100(.33-.25)/.25 = 32%
average = sum/4 = 75%
Always up, but 1970 to 1980 is so big an increase it dominates the statistics. (That is when gas prices went crazy by the way)
Please help I’m struggling with how to find the percent of change each decade and how to predict a future price. I can’t find any examples of this lesson for help
Directions: You probably see them in the news all the time—predictions about prices, jobs, stocks, and other aspects of the economy. Now it's your turn to predict the future! Follow the directions to make and explain an economic prediction for an article you have been asked to write in the Economic News.
1. Choose one item of interest to you in the Historical Pricing Chart on the next page.
2. Calculate the percent of change of the item's price each decade, and use your results to determine the average rate of change from 1960–2000.
3. Comment on the trend in your item’s percent of increases.
4. Go shopping! Find the average current price of your item online, in the newspaper, or locally by looking at the price when you go to the store in the next day or two. Does the current price match the trend from 1960–2000 that you identified? Explain your thinking.
5. Create a line graph or other visual model to show the pricing trend. Be sure to include the current price in your model.

I believe U.S. Postage Stamps are the easiest. The price change is consistent and only increases, so it should be easier to do (easier than the other ones, anyway). That's what I'm doing.
