An instructor would like ot keep track of abscences in the gradebook and apply a penalty depending on the days missed. Here is the breakdown:
2 days missed - 0% penalty
3 days missed - 5% penalty
For each day after 3 days missed he wants an additional 2.5% added to the previous penalty. For example, 4 days missed - 7.5% penalty.
I have not been able to find a way to get this to work. Does anyone know of a way to get this to work. Any help would be appreciated.
