Let's examine the history of LSUS undergraduate enrollment vs. its tuition and fees.The data provided will show you historical information on LSUS undergraduate enrollment, total credit hour production, and (12-hour, undergraduate) tuition and fees.

Calculate annual elasticities for both types of quantity variables (i.e., you will have an elasticity of price vs. headcount, and one of price vs. credit hour). You will get an error message in your calculations when the tuition doesn't change (like in 2006-2007), since the elasticity calculation will be trying to divide by zero; just delete those error values in your Excel table so that the cells are blank. The first headcount elasticity will be calculated based on the 2003 and 2004 values of tuition and headcount and should be about 0.978; the first credit hour elasticity will also be based on the 2003 and 2004 values and should be about 0.074 (yes; they are both positive). Calculate the average annual elasticity for headcount (from 2003-2021), and the average annual elasticity for credit hour (from 2003-2021).

Many administrators argue that, to increase revenue to LSUS to cover budget shortfalls, tuition should be raised. Comment on this suggestion, using the evidence you've uncovered.
