Percent Change of the Income Tax Rate in Illinois

In July 2017 the Illinois State Legislature raised the income tax rate from 3.75% to 4.95%.  This change can be described two ways.  “The tax rate increased by 1.2 percentage points.”  or  “The tax rate increased 32%.”

Percent change = change/original = 1.2/3.75 = .32 = 32%

Percent change is the primary way that we (and the media) describe change. When the data itself is a percent, it can be a bit confusing.

Extra Credit Opportunity

As discussed on 1/18/17, you may earn 5 pts of extra credit (to be added to the total of your exam scores). On Monday, 1/23/17, after class those interested will meet in MRO (MG 209) to make some ‘fuzzy stick’ number lines. Dr. O will bring all the supplies. Just show up. If you make a fuzzy stick number line you get 5 pt. You can make a second one, if you wish, to keep.

This is not required.
