opens on day 1 with 6000 shares at $4.60 per share. The price of stock ABC

on day 8 begins at $3.50. The price of stock XYZ on day 8 begins at $3.90.

Stock QRS opens on day 8 with a price of $4.50 per share. Assume that each

stock has the same number of shares that it opened with on day 1. What is

the rate of change of this simple index over 1 week?
