You may take Exam I early

Some students are interested in attending the Kappa Delta Pi International Honors Society in Education Conference in Horrabin Hall on Friday, Sept. 21.  Our class (and Exam I) conflicts with some of the conference sessions.

If you would like to take Exam I early, I can set up a time for you to take it in my office on Thursday (we’ll find a time) or on Friday morning at 11 a.m.

If you’d like to do this, make arrangements with me (Dr. Olsen).

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.
