A radio station has three types of promotional items; Cds, hats and flying disks. Cd's are worth $4.50, hats are worth $3.25, and flying disks are worth $1.25. They have given away 11 CDs, 26 hats, and 53 flying disks. Organize the information using matrices. Then use matrix multiplication to find the station's cost for the promotional items.

Suppose there is a simple index of three stocks, stock abc, stock xyz, and stock qrs. stock abc opens on day 1 with 4000 shares at $3.15 per share. stock xyz opens on day 1 with 5000 shares at $4.30 per share. stock qrs 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?
