The perfentage of residents in a city in Shreveport who recycle increased from 28.3% in 2000 to 31.1% in 2007. Predict the percentage of residents who will recycle in 2017.
To predict the percentage of residents who will recycle in 2017, we can analyze the trend between 2000 and 2007 and make an assumption for the following years.
Given that the percentage of residents who recycle increased from 28.3% in 2000 to 31.1% in 2007, we can calculate the average increase per year over that period.
First, we need to determine the number of years between 2000 and 2007:
2007 - 2000 = 7 years
Next, we calculate the average increase per year:
(31.1% - 28.3%) / 7 years = 0.028% per year
Now, we can use this average increase to estimate the percentage of residents who will recycle in 2017.
Start with the percentage in 2007:
31.1%
Then, calculate the increase over 10 years (2007-2017):
0.028% * 10 years = 0.28%
Add this increase to the percentage in 2007:
31.1% + 0.28% = 31.38%
Therefore, our prediction is that approximately 31.38% of residents in Shreveport will recycle in 2017.
