I am supposed to do this: 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.
6. Predict the item's price at a future date. Use your calculations and visual
model to justify your prediction.
7. Organize your analysis, prediction, explanations, and visual model in a brief
news article. Your completed article will be submitted as your portfolio
assessment.
and this is what I wrote down, but I'm not sure if it makes sense: 1960-1970 percent of change:0.36-0.25=0.11*100 /0.25= 44% change increase
1970-1980 percent of change:1.19-0.36=0.83*100=83/0.36 =230.5% percent increase
1980-1990 percent of change:1.35-1.19=0.16 *100=16/1.35=11.8% increase
1990-2000 percent of change:1.35-1.26=0.09*100=9/ 1.35=6.6 percent decrease
Now i will do 44+230.5+11.8 +6.6= 292.9 /4 = 73.2 so the average rate of change is 73% or 19.8 cents per year
Well, only 1960-1970 and 1970-1980 and 1980-1990 is a percent of increase. I notice that as society progressed in the 1960s -2000 they started to increase the cost which made the percent of increase go up especially in 1970-1980
Now a gallon of gas is about 3.30 dollars I am guessing because of the disease that started in 2020 because people aren't working and businesses closing down
I definitely think it's going to go up to 4 dollars
0.25 would be worth less now a days that why prices are going up over the years
i know its a lengthy read but please help
