Explanation:

The Consumer Price Index (CPI) is a measure that examines the weighted average of prices of a basket of consumer goods and services, such as transportation, food, and medical care. It is calculated by taking price changes for each item in the predetermined basket of goods and averaging them.

Solution

CPI =  New Price/ Old Price

Where:

Old Price = $0.15 New Price =$0.50

∴ = 0.50/0.15

CPI = 3.33

Then there was no significant rise on inflation since the CPI for 37 years was 3.33
