How could you tell if movies have increased in price faster or slower than most goods and services?

Example: How could you tell if movies have increased in price faster or slower than most goods and services? To convert that price into today's dollars, use the CPI.

Let's say your parents told you that in 1950 a movie cost 25 cents. How could you tell if movies have increased in price faster or slower than most goods and services? To convert that price into today's dollars, use the CPI.

The CPI for 1950 = 24.1
The CPI for 2007 = 205.5
A movie in 1950 = $0.25
Use the following formula to compute the calculation:
2007 Price = 1950 Price x (2007 CPI / 1950 CPI)
$2.13 = $0.25 x (205.5/ 24.1)
A full-price movie at a Minneapolis theater costs between $6.00 and $9.00. Looks like movies have increased in price faster than most other goods and services.
