- The Consumer Price Index provides a means of determining the purchasing power of the U.S. dollar from one year to the next. To use the Consumer Price Index to predict a price in a particular year, we can set up a proportion and compare it with a known price in another year as follows:(price in year A)/(index in year A)=(price in year B)/(index in year B)In 1986 the Consumer Price Index was 109.6 and in 2010 it was 218.1. Find the amount that would be charged in 2010 for the use of the same amount of electricity that cost $110 in 1986.
