Solutions to the first midterm

Here are the solutions to the first midterm.

There was a slight curve on the midterm.  To calculate this curve, what I did was to first add up the points from the problems you solved.  That "total" I then multiplied by 4/5 and added 20.  I then rounded to the nearest whole number.  The curved grade is the circled one on your exam, and that's what I entered into Canvas.

The average grade on the exam (after the curve) was 80.
