Percent and Trends

Question

If a movie ticket costs $0.69 in 1960, $1.55 in 1970, $2.60 in 1980, $4.23 in 1990 and $5.39 in 2000, what is the average rate of change from 1960 to 2000. 

 

This problem is on my extra credit study guide, and I am unsure how to solve it. Can somebody please show the steps of solving this?

Scott,

 

Average Rate of Change over a function is change in Y/change in X.  Make sure to take only the end points of the interval.
