Question

From 2015 to 2016, the overall price level rose from 200 to 220. Over the same period, tuition rates at the local community college rose from $100 to $115 per credit hour. What can be concluded from the rise in tuition relative to overall inflation?

Answer 1

We can conclude that tuition rates at the local community college are rising faster than overall inflation.

This is because from 2015 to 2016, the overall price level rose 10%, from 200 to 2020 (20 is the 10% of 200), while tuition rates rose 15% in the same period, from $100 to $115 (15 is obviously the 15% of 100).
