Quizplus · Accepted Answer

To calculate the percent change in prices from 2010, we divide the CPI of the current year by the CPI of the base year (2010) and multiply by 100. 
For example, to find the percent change in prices in 2015: (232.957/182.997) x 100 = 127.27
This means that prices have increased by 27.27% from 2010 to 2015. 
We can repeat this calculation for all the other years and find the following percent changes:
- 2011: 140.31%
- 2012: 153.77%
- 2013: 164.89%
- 2014: 173.71%
- 2015: 127.27%
Taking the average of these percent changes gives us:
(140.31 + 153.77 + 164.89 + 173.71 + 127.27)/5 = 152.39%
Therefore, prices have risen by approximately 152.39% from 2010 to 2015, which is closest to choice B (28%).
