1. Choose one item of interest to you in the Historical Pricing Chart on the next
page. ( the one I have chosen is listed below)

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.

Answer 1

Answer: 75%

Step-by-step explanation:

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.

I hope this helps (I believe this is right)
