To find the net change in price of the stock for the week, let's break down the changes for each day and sum them up.

Day-by-day changes:

1. Monday: Up 4 points → $+4$
2. Tuesday: Down 6 points → $-6$
3. Wednesday: Up 3 and 1/2 points → $+\frac{7}{2} = +3.5$
4. Thursday: Up 1 and 1/4 points → $+\frac{5}{4} = +1.25$
5. Friday: Down 5 and 1/8 points → $-\frac{41}{8} = -5.125$

Now, sum all the changes: $4 + (-6) + 3.5 + 1.25 + (-5.125) = -2.375$

Net change:

The net change in price of the stock for the week is -2.375 points (a decrease of 2.375 points).
