Solution
The Consumer Price Index (CPI) is a measure that examines the weighted average of prices of a basket of consumer goods and services. It is calculated by taking price changes for each item in the predetermined basket of goods and averaging them.
Here's how you calculate it:
-
Find the cost of the market basket of goods in the base year. In this case, it's $200 billion in year 1.
-
Find the cost of the same market basket of goods in the year you are measuring. In this case, it's $220 billion in year 2.
-
Divide the cost of the market basket in the year you are measuring by the cost in the base year. So, 200 billion = 1.1
-
Multiply this number by 100 to get the CPI. So, 1.1 * 100 = 110.
So, the CPI for the economy in year 2 is 110.
