Answer:
It means movies are relatively cheaper than working hours
Explanation:
In order to estimate the relativity of the two activities, there is a need to compare the changes over ten years
1. 10 years ago, Movie ticket= $5, 10 Years later Movie ticket= $8, the 10 year difference is $3
2. 10 years ago, average hourly wage = $10, 10 years later, average hourly wage = $20, the 10 year difference is $10
First, it means for the $3 change in movie ticket cost, there was a $10 change in the average hourly wage.
Put differently, while movie ticket got a 60% increase in price 3/5 x 100=60%
Average hourly wage got 100% increase 10/10 x 100= 100%
It means that working hours got more expensive and movie tickets got cheaper
